Abstract

It is an object of the present invention to provide a semispherical shoe which can be prevented from being subjected to seizure even in a dry lubrication state in which there is no lubricating oil at the start time of an operation of a swash plate compressor, is excellent in its sliding contact property and load resistance, does not deteriorate in its lubricating property due to generated frictional heat, does not subject a resin layer to peeling from a base material, and ensures sufficient durability. It is another object of the present invention to provide a swash plate compressor in which a lubricating film is not formed on a sliding contact surface of the swash plate and that of a piston owing to the use of the semispherical shoe. A semispherical shoe (4) is subjected to sliding contact with the swash plate of the swash plate compressor and the piston thereof. Abase material (5) consists of a metallic member. A resin layer (6b) is formed on a surface of a planar part (4b) to be subjected to sliding contact with the swash plate. A resin layer (6a) is formed on a surface of a spherical part (4a) to be subjected to sliding contact with the piston. The resin layer (6a) and the resin layer (6b) are integral with each other. At least one portion of the base material (5) is not covered with the resin layer (6) and is exposed.
