摘要:
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, does not deteriorate in its lubricating property owing to frictional heating, and ensures sufficient durability and a swash plate compressor in which a lubricating film is not formed on a sliding contact surface of a swash plate owing to the use of the semispherical shoe. A semispherical shoe (4) makes sliding contact with the swash plate of the swash plate compressor. A surface of a planar part (4b) which makes sliding contact with the swash plate consists of a resin layer (10). A surface of a spherical part (4b) consists of a base material of the semispherical shoe. In viewing the surface of the planar part divided into three parts consisting of a central part (10a), an outer edge part (10c), and an intermediate part (10b) interposed between the central part (10a) and the outer edge part (10c) in a direction vertical to the surface of the planar part, an annular belt portion (10d) whose layer thickness is larger than that of each of the central part (10a) and the outer edge part (10c) is formed inside the intermediate part (10a).
