A variable displacement compressor that varies its displacement by altering the inclination of a swash plate. A drive shaft is supported rotatably within a housing. A rotor is fixed to the drive shaft. A swash plate is mounted on the drive shaft and adapted to slide and incline with respect to the shaft. A hinge mechanism operably connects the swash plate to the rotor. A plurality of pistons, each accommodated in one of the bores and coupled to the swash plate, are reciprocated in the bore by the rotation of the swash plate. The hinge mechanism includes a guide pin that projects from the swash plate and includes a joint. A support arm projects from the rotor. The support arm includes a receptacle which accommodates the joint and extends toward the drive shaft. A bushing is accommodated within the receptacle and slides along a wall of the receptacle. The bushing is provided with an interior space to accommodate the joint. The interior space allows the joint to pivot therein when the inclination of the swash plate is altered. The bushing is provided with a slit to permit the interior space to be temporarily enlarged when attaching the bushing to the joint.
