A shoe 5 includes a spherical portion 5A in sliding contact with a sliding surface 4a that is a hemispherical concave portion of a piston 4, an end surface portion 5B in sliding contact with a swash plate 3, and a circular cylindrical portion 5C formed between the spherical portion 5A and the end surface portion 5B. A plurality of linear oil grooves 5F are formed in the outer peripheral surface of the cylindrical portion 5C. A lubricant oil separated from a refrigerant is held in each of the oil grooves 5F of the cylindrical portion 5C of the shoe 5 when a swash plate compressor 1 is in a non-operating state. When the swash plate compressor 1 is started, the lubricant oil in the oil grooves 5F is fed to the spherical portion 5A and the end surface portion 5B which are sliding portions. The shoe 5 having excellent lubricity in comparison with a conventional case can be thereby provided. |
