ABSTRACT:
A drive hub-receiving surface 40c of a thrust flange 40 is set substantially at a right angle to the axis of a shaft 5, whereby when the compressor drastically enters the maximum delivery quantity condition, an abutment portion 41c of a drive hub 41 substantially perpendicularly abuts on the drive hub-receiving surface 40c of the thrust flange 40. This prevents load from perpendicularly acting on the shaft 5, causing substantially no elastic deformation of the shaft 5. Further, under the maximum delivery quantity condition, the abutment portion 41c of the drive hub 41 perpendicularly abuts on the drive hub-receiving surface 40c, so that compression reaction forces acting from a piston 7 to the drive hub 41 are absorbed by the drive hub-receiving surface 40c of the thrust flange 40, thereby decreasing the vibration of the drive hub 41.
