Abstract
A semi-spherical shoe includes an end face B which is disposed in sliding contact with a swash plate and a semi-spherical surface A which is disposed in sliding contact with a semi-spherical recess A formed in a piston . A spherical recess C is formed in the top portion of the semi-spherical surface A to define a space which serves as a reservoir of lubricant oil between the spherical recess C and the semi-spherical recess B. If the volume of the space which serves as a reservoir of lubricant oil is increased, an accumulation of abraded power in the spherical recess C which forms the space can be prevented in a favorable manner.
