A shoe for use in a swash-plate type compressor and made of a base material of steel, is slidably disposed between the swash-plate and a steel ball rotatably supported in a recess of a piston and is provided on one side thereof with a lining of copper or a copper alloy for slidably contacting with the sliding surface of the swash-plate and further provided on the other side thereof with a covering or a coating layer of a metal selected out of copper, copper alloys, aluminum, aluminum alloys, zinc, zinc alloys, nickel, chromium, and like metals, each of these metals being a material substantially free from seizure with steel, over a substantially spherical concave surface of the shoe thus permitting the steel ball to slidably rotate in relation thereto.
