PROBLEM TO BE SOLVED: To provide a hemispherical shoe, in which a seizure does not occur even in a dry lubrication state having no lubricant at an operation starting time, and which has neither a drop of lubrication property due to friction exothermic heat nor separation of a resin layer so that the durability is sufficiently retained, and a swash plate type compressor, in which a lubricant coat is removed from the sliding face of a swash plate or a piston by using that hemispherical shoe.SOLUTION: A hemispherical shoe 4 slides on a swash plate and a piston of a swash plate type compressor, and a metallic member is used as a base material 5. A resin layer 6b is formed on the surface of a flat part 4b to slide with the swash plate, and a resin layer 6a is formed on the surface of a spherical part 4a to slide with the piston. The individual thicknesses of the resin layer 6a and the resin layer 6b are 0.1 to 0.7 mm. The resin layer 6a and the resin layer 6b are integrally formed by injection molding on the surface of the base material 5 by using a resin composition using an aromatic polyetherketone as a base resin.SELECTED DRAWING: Figure 2 |
