ABSTRACT:
A shoe-and-socket joint, which is incorporated into a swash plate type compressor as a drive force transmitting unit arranged between a rotational swash plate and each of a plurality of reciprocal pistons, has a shoe provided with a spherically formed contact face and a recessed curved socket, for example, an ellipsoidal socket, deviated from a spherical form. Therefore, there is provided a wedge-shaped clearance between the socket and the shoe. An oil containing refrigerant gas flows enough into between the socket and the shoe to achieve a good lubrication.
