A swash plate is operably connected through a lug plate and a hinge mechanism to a drive shaft, and slidably retained on an end part of each piston through a pair of front and rear shoes. A rotational motion of the swash plate following rotation of the drive shaft is converted through the shoes into a reciprocating motion of each piston. A thermoplastic polyimide coating is formed on the swash plate and the shoes as sliding components of a compressor. The thermoplastic polyimide coating may contain a solid lubricant. For the solid lubricant, for example, polytetrafluoroethylene is used. Thus, it is possible to obtain a compressor, which includes the sliding components having improved sliding characteristics, and is manufactured relatively easily.
