Abstract (en)
An impeller(30,130) is fixed to a shaft(41) concentric with a center axis(J) extending in an up-down direction and is rotatable about the center axis(J) together with the shaft(41). The impeller(30,130) includes a boss portion (34) which is fixed to the shaft(41) and extends in an axial direction, an impeller body portion (31), a plurality of blade portions (32) arranged on an upper surface of the impeller body portion (31), and a rib portion (35, 135) arranged on a lower surface of the impeller body portion (31). The impeller body portion (31) extends downward from an upper end of the boss portion (34) while being widened in a radial direction, and is arranged to surround the boss portion (34) in a circumferential direction. When viewed in the axial direction, a front side end portion of the rib portion (35, 135) is curved toward a rotation direction back side as the rib portion (35, 135) extends from a radial inner side toward a radial outer side.
