(54)	Swash plate type compressor having an improved torque transmission mechanism between a shaft and a swash plate

(57) In a swash plate type compressor win which a hinge mechanism (6) supporting a swash plate (5) on a shaft (4) in such a manner that the swash plate has an inclination angle variable relative to the axial direction, the hinge mechanism serves to transmit a driving torque of the shaft to the swash plate and comprises a fixed hinge (7) fixedly connected to the shaft and a movable hinge (8) fixedly connected to the swash plate. The fixed hinge has a fixed arm (72). The movable hinge has a movable arm (82) which is coupled to the fixed arm to be pivotal around an axis extending perpendicular to the axial direction. The fixed and the movable arms transmit a part of the driving torque to the swash plate in cooperation with each other. Further, the fixed hinge has an auxiliary fixed coupling portion (73). The movable hinge has an auxiliary movable coupling portion (86) engaged with the auxiliary fixed coupling portion. With this arrangement, another part of the driving torque is transmitted from the shaft to the swash plate in cooperation of the auxiliary fixed and the auxiliary movable coupling portions.
