[0012] The window glass raising/lowering device 1 is mounted to a predetermined mounting object, and raises and lowers the window glass W. The window glass raising/lowering device 1 of the present embodiment is mounted, for example, to a mounting object such as a door panel of a vehicle body. The window glass raising/lowering device 1 may be mounted to another mounting object other than the vehicle body. Incidentally, a side to which the window glass W is raised when the window glass raising/lowering device 1 is mounted to the mounting object is called an "upper side", and a side to which the window glass W is lowered is called a "lower side" regarding the respective members of the window glass raising/lowering device 1 in the present specification.

[0013] The drive unit 5 generates a driving force to rotate the drum 4. The drive unit 5 has a driving force generation device such as an electric motor and a manually operated handle. In the present embodiment, the drive unit 5 includes an electric motor 51 and a shaft 52 (see Fig. 6) which is connected to the drum 4 and rotates the drum 4 by the driving force of the electric motor 51 as illustrated in Fig. 1. Incidentally, the drive unit 5 is not limited to the illustrated shape or structure as long as it is possible to generate the driving force to rotate the drum 4. Although the drive unit 5 is provided in the vicinity of the center in a longitudinal direction of the guide portion 7 illustrated as a guide rail in the present embodiment, but the position at which the drive unit 5 is provided is not limited. For example, the drive unit 5 may be provided at a lower end of the guide portion 7 or the like.

[0014] The drum 4 is rotated in forward and reverse directions about a center axis X of the drum 4 (hereinafter referred to as a drum center axis) by the drive unit 5, thereby moving the moving member 2 by winding and unwinding the cable 3 connected to the drum 4. In the present embodiment, the drum 4 is a substantially cylindrical member, and has an axial hole 41 to which the shaft 52 (see Fig. 6) is insertable and which is engaged with the shaft 52. When the shaft 52 is rotated by the driving force of the drive unit 5, the drum 4 is rotated as illustrated in Figs. 4 and 6.

[0015] The cable 3 is wound around the drum 4 and unwound from the drum 4 along with the rotation of the drum 4. The cable 3 is connected to the drum 4 and the moving member 2. As the cable 3 is operated by the rotation of the drum 4, the moving member 2 connected to the cable 3 is raised and lowered. In the present embodiment, the cable 3 has a first cable 31 and a second cable 32 as illustrated in Fig. 1. One end (not illustrated) of each of the first cable 31 and the second cable 32 is connected to the drum 4. Each of other ends 31E and 32E of the first cable 31 and the second cable 32 is connected to the moving member 2. In the present embodiment, the first cable 31 and the second cable 32 extend from the drum 4 toward the direction changing member 8, and are changed in direction by the direction changing member 8 to extend toward the moving member 2. In the present embodiment, the first cable 31 is a raising cable. When the first cable 31 is wound around the drum 4, the moving member 2 is pulled upward by the first cable 31 and moves in a raising direction. With the movement of the moving member 2 in the raising direction, the window glass W mounted to the moving member 2 is raised. The second cable 32 is a lowering cable. When the second cable 32 is wound around the drum 4, the moving member 2 is pulled downward by the second cable 32 and moves in a lowering direction. With the movement of the moving member 2 in the lowering direction, the window glass W mounted to the moving member 2 is lowered. Incidentally, a publicly-known control cable can be used as the cable 3. For example, the first cable 31 and the second cable 32 can be used as inner cables of a control cable. As illustrated in Fig. 1, the first cable 31 and the second cable 32 may be partially inserted into an outer casing 33 in a routing path. In addition, the cable 3 is configured using the two cables in the present embodiment, but may be configured using one cable.

[0016] The moving member 2 is operated by the cable 3 to be raised and lowered, thereby raising and lowering the window glass W connected to the moving member 2. The window glass W is directly or indirectly mounted to the moving member 2 as illustrated in Fig. 1. In the present embodiment, the moving member 2 is mounted to the guide portion 7 so as to be movable along the longitudinal direction of the guide portion 7. As illustrated in Fig. 1, the moving member 2 includes: a first connection portion 21a to which the end 31E of the cable 3 is connected; a second connection portion 21b to which the end 32E of the cable 3 is connected; and a window glass mounting portion 22 to which a lower end of the window glass W is mounted. Incidentally, a shape and a structure of the moving member 2 are not limited to those illustrated in the drawings. In addition, the moving member 2 is guided by the guide portion 7 in the present embodiment, but the moving member 2 may move without being guided by the guide portion 7.

[0017] The housing 6 accommodates the drum 4 to be rotatable. The housing 6 is directly or indirectly mounted to a mounting object such as a door panel (not illustrated). In the present embodiment, the window glass raising/lowering device 1 has a base body 9 to which the housing 6 is mounted as illustrated in Figs. 1, 3, and 4. In the present embodiment, the housing 6 is mounted to the mounting object such as the door panel via the base body 9. Incidentally, the housing 6 may be directly mounted to the mounting object such as the door panel. In such a case, the mounting object itself such as the door panel serves as the base body.

[0018] As illustrated in Fig. 2, the housing 6 includes: an inner space portion 61 (see Fig. 5) having an accommodating portion 611 in which the drum 4 is accommodated; a cable lead-in/out portion 62 through which the cable 3 is led in and out; and an opening portion 63 that communicates the inner space portion 61 with the outside. In addition, the housing 6 includes a protruding portion 64 which extends to an opposite side of the drum 4 in a direction of the drum center axis X, on a radially outer side of the opening portion 63 with respect to a position of the drum center axis X as illustrated in Figs. 2 and 3. The housing 6 has an insertion port 6a (see Figs. 4 and 5) through which the drum 4 can be inserted into the inner space portion 61. In the present embodiment, the housing 6 includes a housing base 65, and the housing base 65 is provided with the accommodating portion 611, the cable lead-in/out portion 62 and the like as illustrated in Fig. 2. The housing base 65 has a connection portion 65a configured to mount the housing 6 to the base body 9. The connection portion 65a is fixed to a connected portion 91 provided on the base body 9 by a publicly-known fixing member such as a bolt, a nut, and a screw.

[0019] The inner space portion 61 is a part which forms an inner space provided in the housing 6 that includes the accommodating portion 611 which forms a space in which the drum 4 is accommodated as illustrated in Fig. 5. The inner space portion 61 may include other spaces such as radial spaces S21 and S22 and axial spaces S31 and S32, which will be described later, in addition to an accommodating space S1 of the accommodating portion 611 as illustrated in Fig. 5.

[0020] The accommodating portion 611 accommodates the drum 4 to be rotatable. As illustrated in Figs. 5 and 6, the accommodating portion 611 has a circumferential wall 611a opposing an outer circumferential surface 42 (see Fig. 6) of the drum 4 and a bottom 611b opposing one end surface 4a of the drum 4. A recess defined by an inner surface IS of the circumferential wall 611a and the bottom 611b serves as the accommodating space S1 in the accommodating portion 611.

[0021] In the present embodiment, the inner space portion 61 includes not only the accommodating space S1 of the accommodating portion 611 but also the radial spaces S21 and S22, which extend to the radially outer side of the drum 4 to communicate with the accommodating space S1 of the accommodating portion 611, at an end on the base body 9 side in the direction of the drum center axis X as illustrated in Fig. 6. In addition, the inner space portion 61 includes the axial spaces S31 and S32, which extend in the direction of the drum center axis X between an inner surface 64a of the protruding portion 64 and an outer surface OS of the circumferential wall 611a, at parts where the opening portion 63 and the protruding portion 64 are provided as illustrated in Figs. 5 and 6. The radial spaces S21 and S22 and the axial spaces S31 and S32 will be described later.

[0022] One side of the inner space portion 61 in the direction of the drum center axis X (a side of the one end surface 4a of the drum 4) is covered by the bottom 611b except for a region of the opening portion 63 as illustrated in Figs. 5 and 6. The other side of the inner space portion 61 in the direction of the drum center axis X (a side of another end surface 4b of the drum 4) opens in the insertion port 6a as illustrated in Fig. 5 in a state where the base body 9 is not mounted. In the present embodiment, the base body 9 has a cover portion 92 that covers the insertion port 6a such that the drum 4 is not detachable from the housing 6 as illustrated in Figs. 3, 4 and 6. As the base body 9 is mounted to the housing 6, the insertion port 6a is covered by the cover portion 92 in a state where the drum 4 is accommodated in the accommodating portion 611. Incidentally, the base body 9 has the mounting portion 93 which mounts the window glass raising/lowering device 1 to a mounting object, such as a door panel, in the present embodiment. The mounting portion 93 is formed in an arm shape extending in a direction away from the housing 6 with respect to the plate-shaped cover portion 92. Incidentally, the shape of the base body 9 is not particularly limited as long as it is possible to mount the housing 6.

[0023] The cable lead-in/out portion 62 leads the cable 3 to the outside of the housing 6 and leads the cable 3 to the inside of the housing 6. The cable lead-in/out portion 62 has a communication passage to communicate the accommodating portion 611 in which the drum 4 is accommodated with the outside of the housing 6, and the cable 3 is led out of the housing 6 and led into the housing 6 through the communication passage. As illustrated in Figs. 1 and 2, the cable lead-in/out portion 62 includes a first cable lead-in/out portion 62a and a second cable lead-in/out portion 62b. In the present embodiment, the outer casing 33 is connected to each of the first and second cable lead-in/out portions 62a and 62b, and the cable 3 is inserted into the outer casing 33 through the first and second cable lead-in/out portions 62a and 62b and extends toward the moving member 2.

[0024] The first cable lead-in/out portion 62a and the second cable lead-in/out portion 62b are provided in the housing 6 so as to be arranged such that each position thereof when the housing 6 is rotated by 180° about the drum center axis X (position illustrated by the two-dot chain line in Fig. 2) becomes line-symmetric (hereinafter simply referred to as line symmetry) with respect to a position of the other cable lead-in/out portion in a state before the rotation by 180°(hereinafter simply referred to as line symmetry). Therefore, for example, in a mounting object for which a pair of the housings 6 are provided at symmetrical positions, such as a left door and a right door of a vehicle, the same housing 6 can be shared by vertically reversing the housing 6 provided on the left side and the housing 6 provided on the right side. Incidentally, the entire housing 6 does not have to be completely line-symmetric as long as the housing 6 includes the first cable lead-in/out portion 62a and the second cable lead-in/out portion 62b arranged with the line symmetry such that the pair of housings arranged at symmetrical positions can be shared.

[0025] The opening portion 63 has a first opening portion 63a and a second opening portion 63b as illustrated in Fig. 2. The first opening portion 63a and the second opening portion 63b are provided on the radially outer side with respect to the position of the drum center axis X. The first opening portion 63a is provided on the upper side with respect to the position of the drum center axis X when the first cable lead-in/out portion 62a is on the upper side, and on the lower side with respect to the position of the drum center axis X when the first cable lead-in/out portion 62a is on the lower side. In addition, the second opening portion 63b is provided on the upper side with respect to the position of the drum center axis X when the second cable lead-in/out portion 62b is on the upper side, and on the lower side with respect to the position of the drum center axis X when the second cable lead-in/out portion 62b is on the lower side.

[0026] As a result, any one of the first opening portion 63a and the second opening portion 63b is positioned on the lower side with respect to the position of the drum center axis X. Therefore, when water that has entered the inner space portion 61 flows downward below the drum center axis X, the water can be discharged to the outside of the inner space portion 61 through the opening portion 63.

[0027] The positions of the first opening portion 63a and the second opening portion 63b are not particularly limited as long as it is possible to communicate the inside of the inner space portion 61 with the outside of the inner space portion 61 and to discharge the water having entered the inner space portion 61 to the outside of the inner space portion 61 when positioned on the lower side with respect to the position of drum center axis X. In the present embodiment, the first opening portion 63a and the second opening portion 63b are provided to be opened at a position of a lower end of the circumferential wall 611a when positioned on the lower side with respect to the position of the drum center axis X as illustrated in Fig. 2. In this case, the first opening portion 63a and the second opening portion 63b open at a place where the water entered into the inner space portion 61 is collected downward along the circumferential wall 611a. Therefore, the water having entered the inner space portion 61 can be easily discharged.

[0028] Each shape and each size of the first opening portion 63a and the second opening portion 63b are not particularly limited as long as the first opening portion 63a and the second opening portion 63b have predetermined shape and sizes that can smoothly discharge the water having entered the inner space portion 61. Incidentally, the first opening portion 63a and the second opening portion 63b are provided such that an upper end and a lower end portion of the bottom 611b are penetrated in the direction of the drum center axis X, and an upper end and a lower end portion of the circumferential wall 611a are penetrated in a radial direction of the drum 4 in the present embodiment as illustrated in Figs. 2 and 5.

[0029] The protruding portion 64 has a first protruding portion 641 and a second protruding portion 642 as illustrated in Figs. 1 and 2. The first protruding portion 641 extends to the opposite side of the drum 4 in the direction of the center axis X (the left side of the one end surface 4a of the drum 4 in Fig. 6) on the radially outer side of the first opening portion 63a with respect to the position of the drum center axis X as illustrated in Fig. 6. That is, the first protruding portion 641 is provided to cover the first opening portion 63a from the radially outer side of the drum 4 toward a radially inner side. The first protruding portion 641 is provided between the first protruding portion 641 and the first opening portion 63a such that a predetermined interval is formed in the radial direction of the drum 4. Although it is sufficient to provide the first protruding portion 641 so as to cover at least a position where the first opening portion 63a is provided, in the direction of the drum center axis X, it is preferable that the first protruding portion 641 extend to the opposite side of the drum 4 beyond the first opening portion 63a in the direction of the drum center axis X.

[0030] The first protruding portion 641 is provided on the upper side of the first opening portion 63a when the first opening portion 63a is on the upper side, and on the lower side of the first opening portion 63a when the first opening portion 63a is on the lower side. When the window glass raising/lowering device 1 is mounted to a mounting object, the first protruding portion 641 covers the first opening portion 63a from the upper side of the first opening portion 63a if the first opening portion 63a is positioned on the upper side with respect to the drum center axis X. If the first opening portion 63a is positioned on the lower side with respect to the drum center axis X, the first protruding portion 641 is arranged below the first opening portion 63a.

[0031] As illustrated in Fig. 6, the second protruding portion 642 extends to the opposite side of the drum 4 in the direction of the drum center axis X, on the radially outer side of the second opening portion 63b with respect to the position of the drum center axis X. That is, the second protruding portion 642 is provided to cover the second opening portion 63b from the radially outer side of the drum 4 toward the radially inner side. The second protruding portion 642 is provided between the second protruding portion 642 and the second opening portion 63b such that a predetermined interval is formed in the radial direction of the drum 4. Although it is sufficient for the second protruding portion 642 to extend so as to cover at least a position where the second opening portion 63b is provided, in the direction of the drum center axis X, it is preferable that the second protruding portion 642 extend to the opposite side of the drum 4 beyond the second opening portion 63b in the direction of the drum center axis X.

[0032] The second protruding portion 642 is provided on the upper side of the second opening portion 63b when the second opening portion 63b is on the upper side, and on the lower side of the second opening portion 63b when the second opening portion 63b is on the lower side. When the window glass raising/lowering device 1 is mounted to a mounting object, the second protruding portion 642 covers the second opening portion 63b from the upper side of the second opening portion 63b if the second opening portion 63b is positioned on the upper side with respect to the drum center axis X. If the second opening portion 63b is positioned on the lower side with respect to the drum center axis X, the second protruding portion 642 is arranged below the second opening portion 63b.

[0033]  Each of the first protruding portion 641 and the second protruding portion 642 has the inner surface 64a and an outer surface 64b as illustrated in Fig. 2. The inner surface 64a is a surface of the protruding portion 64 that faces a surface on the side of the opening portion 63, that is, a surface that faces the outer circumferential surface 42 of the drum 4. In addition, the outer surface 64b is a surface of the protruding portion 64 on the side opposite to the inner surface 64a, that is, the surface of the protruding portion 64 that is farther from the drum center axis X.

[0034] The inner surface 64a has a drainage guide portion G that guides water, which has moved from the inner space portion 61 of the housing 6 to the opening portion 63 when the protruding portion 64 is on the lower side, to the outside of the housing 6 as illustrated in Fig. 2. In addition, the outer surface 64b has a weir D that moves water adhering to the outer side of the protruding portion 64 downward when the protruding portion 64 is on the upper side as illustrated in Fig. 2. When the water having moved from the inner space portion 61 to the opening portion 63 flows from the opening portion 63 to the protruding portion 64 further downward, the drainage guide portion G guides the water to the outside of the housing 6. The drainage guide portion G prevents water from being accumulated in the inner space portion 61 and the housing 6. The drainage guide portion G is provided with a guide portion that guides water from the opening portion 63 to a side away from the opening portion 63, and keeps the water away from the adjacent opening portion 63. The guide portion has, for example, a concave shape and is provided such that water moves downward. In addition, the weir D causes water flowing from the upper side of the protruding portion 64 to flow downward along the weir D so as to deviate from the opening portion 63, and prevents water from entering the opening portion 63 positioned below the protruding portion 64.

[0035] As described above, the window glass raising/lowering device 1 of the present embodiment is provided in the housing 6 with the arrangement in which the first cable lead-in/out portion 62a and the second cable lead-in/out portion 62b are line-symmetric. As a result, the same housing 6 can be shared by vertically reversing the housing 6 provided on the left side and the housing 6 provided on the right side in the mounting object for which the pair of the housings 6 are provided at symmetrical positions. In addition, the housing 6 includes the first opening portion 63a and the second opening portion 63b that communicate the inside of the inner space portion 61 with the outside of the inner space portion 61. The opening portion 63 positioned on the lower side between the first opening portion 63a and the second opening portion 63b discharges the water that has entered the inner space portion 61. The water discharged from the opening portion 63 on the lower side is guided to the outside of the housing 6 by the drainage guide portion G of the protruding portion 64 positioned on the lower side between the first protruding portion 641 and the second protruding portion 642. Meanwhile, when the housing 6 is shared by the right and left sides of the mounting object, the opening portion 63 is provided on the upper side of the inner space portion 61, but water is prevented from entering from the opening portion 63 on the upper side by the weir D of the upper protruding portion 64 on the upper side of the opening portion 63 positioned on the upper side. In this manner, the window glass raising/lowering device 1 of the present embodiment can share the housing 6 on the right and left sides by vertically reversing the housing 6 and can suppress the entry and accumulation of water inside the inner space portion 61 of the housing 6.

[0036] Specifically, when a pair of the window glass raising/lowering devices 1 is arranged on the right and left sides of a vehicle, for example, the housing 6 is provided on the left side of the vehicle such that the first cable lead-in/out portion 62a, the first opening portion 63a, and the first protruding portion 641 are on the upper side. On the other hand, on the right side of the vehicle, the same housing 6 is provided to be vertically reversed from the housing 6 on the left side such that the second cable lead-in/out portion 62b, the second opening portion 63b, and the second protruding portion 642 are on the upper side. As a result, the housings 6 can be arranged to be laterally symmetric with respect to a moving direction of the vehicle on the right and left sides of the vehicle.

[0037] In addition, for example, in the housing 6 on the left side of the vehicle, the water ran along the cable 3 and the water entering from the upper side of the housing 6 are prevented from entering the inner space portion 61 through the first opening portion 63a by the weir D of the outer surface 64b of the first protruding portion 641. On the other hand, the first protruding portion 641 functioning as the weir D on the left side promotes the discharge of water flowing out of the first opening portion 63a by the drainage guide portion G of the inner surface 64a on the right side of the vehicle. Similarly, in the housing 6 on the left side of the vehicle, the drainage guide portion G of the inner surface 64a of the second protruding portion 642 promotes the discharge of water flowing out of the second opening portion 63b. On the other hand, the second protruding portion 642 functioning as the drainage guide portion G on the left side prevents water from entering the inner space portion 61 from the second opening portion 63b by the weir D of the outer surface 64b on the right side of the vehicle.

[0038] In addition, the first opening portion 63a and the second opening portion 63b are formed, and an air flow from the upper opening portion 63 toward the lower opening portion 63 is likely to occur inside the inner space portion 61 in the present embodiment. Therefore, the flow of water inside the inner space portion 61 is smoother than that in the case where there is only one opening portion, and the drainage from the inner space portion 61 is further promoted.

[0039] In the present embodiment, the protruding portion 64 is provided so as to protrude outward with respect to the drum center axis X as illustrated in Fig. 2. Since the protruding portion 64 protrudes outward, the weir D having an inclined surface, which has a downward slope with respect to a top 64c, is formed on both sides of the top 64c of the protruding portion 64 in the circumferential direction of the drum 4, on the outer surface 64b of the protruding portion 64 when the protruding portion 64 is arranged on the upper side as illustrated in Fig. 2. The water flowing from above in Fig. 2 is likely to flow from the top 64c of the protruding portion 64 along the weirs D on both the sides, and the flow of water toward the upper opening portion 63 is less likely to occur. Therefore, the entry of water from the upper opening portion 63 to the inner space portion 61 is further suppressed. In addition, when the protruding portion 64 is arranged on the lower side, an inclined surface, which has a downward slope toward the top 64c, is provided on both sides of the top 64c of the protruding portion 64 on the inner surface 64a of the protruding portion 64 in the circumferential direction of the drum 4. Therefore, water is collected toward the drainage guide portion G of the inner surface 64a of the protruding portion 64, and drainage is further promoted. The weir D is provided with a guide portion that guides water from above to a side away from the opening portion 63, and keeps water away from the adjacent opening portion 63. The guide portion has, for example, a shape that is convex upward.

[0040]  In the present embodiment, the protruding portion 64 extends to the radially outer side of the drum 4 from the circumferential wall 611a and covers the opening portion 63 in an arched shape such that the opening portion 63 is sandwiched in the circumferential direction of the drum 4 as illustrated in Fig. 2. As a result, the entry of water into the opening portion 63 is suppressed in the circumferential direction of the drum 4 as well as on the radially outer side of the upper opening portion 63. Incidentally, the protruding portion 64 does not necessarily extend from the circumferential wall 611a, and may extend from the housing base 65 in the direction of the drum center axis X independently of the circumferential wall 611a.

[0041] In addition, the base body 9 has a discharge portion 94 which forms, together with the housing 6, a hole capable of discharging water from the inner space portion 61 of the housing 6 in the present embodiment as illustrated in Fig. 6 The discharge portion 94 is a hole to discharge the water which has entered the inner space portion 61 from the base body 9 side. The discharge portion 94 penetrates through the base body 9 (cover portion 92) in a lower part of the inner space portion 61 to communicate the inside of the inner space portion 61 with the outside. Since the discharge portion 94 is provided, the water having moved toward the base body 9 side can be discharged from the discharge portion 94 inside the inner space portion 61 without being directed to the opening portion 63. Therefore, it is possible to further suppress that water from being stored in inner space portion 61.

[0042] In the present embodiment, the inner space portion 61 has the radial space (a first radial space) S21, which extends to the radially outer side of the drum 4 so as to communicate with the accommodating space S1 of the accommodating portion 611, at the end on the base body 9 side in the direction of the drum center axis X as illustrated in Figs. 5 and 6. The radial space S21 forms a recess downward on the lower side of the inner space portion 61, and functions as a water collecting portion to collect water directed toward the base body 9 side of the inner space portion 61 in the direction of the drum center axis X. In the present embodiment, the discharge portion 94 is provided at a position corresponding to the radial space S21, and the water flowing into the radial space S21 is discharged from the inner space portion 61 through the discharge portion 94 by being communicated the radial space S21 with the discharge portion 94. Incidentally, the radial space (a second radial space) S22 extending to the radially outer side of the drum 4 is also provided on the upper side of the inner space portion 61 in the present embodiment. The upper radial space S22 is covered by the cover portion 92 of the base body 9, and water does not enter from the upper side of the inner space portion 61 through the base body 9. Incidentally, when the radial space S22 is arranged on the lower side, the radial space S22 communicates with the discharge portion 94 of the base body 9, and the water flowing into the radial space S22 is discharged from the inner space portion 61 through the discharge portion 94.

[0043] In addition, the inner space portion 61 has the axial space (a first axial space) S31 extending in the direction of the drum center axis X between the inner surface 64a of the protruding portion 64 and the outer surface OS of the circumferential wall 611a, in a part where the lower opening portion 63 and the protruding portion 64 are provided, in the present embodiment as illustrated in Figs. 5 and 6. The axial space S31 communicates with the radial space S21. Water discharged from the inner space portion 61 through the lower opening portion 63 moves to the weir D of the lower protruding portion 64. When the axial space S31 is provided, the water having moved to the weir D moves not only in the direction away from the base body 9 in the direction of the drum center axis X but also to the radial space S21. Therefore, the water having moved to the weir D can move to both the sides in the direction of the drum center axis X, and water can also be discharged directly from the weir D, and water can also be discharged through the axial space S31, the radial space S21, and the discharge portion 94. Thus, even if there is a large amount of water that has entered, the water can be reliably discharged. Incidentally, the axial space (a second axial space) S32, which extends in the direction of the drum center axis X, is provided between the inner surface 64a of the protruding portion 64 and the outer surface OS of the circumferential wall 611a even on the upper side of the inner space portion 61 in the present embodiment. The axial space S32 communicates with the radial space S22. When the axial space S32 is arranged on the lower side, the water can also be directly discharged from the weir D, and the water can be discharged through the axial space S32, the radial space S22, and the discharge portion 94, as in the case of the axial space S31.
