Abstract
A shoe-and-socket joint, which is incorporated into a swash plate type compressor as a drive force transmitting unit arranged between a rotatable swash plate and each of a plurality of reciprocal pistons, has a shoe provided with a spherically formed contact face having a radius R2 and a spherically formed socket recessed in each of the pistons and having a radius R1, the radius R1 being 20 to 150 microns larger than the radius R2, to provide a clearance between the shoe surface and the surface of the socket into which an oil-containing refrigerant can flow to lubricate the shoe surface and the surface of the socket.
