A swash plate type compressor 1 includes a swash plate 3 rotating around a rotating shaft, pistons 4 that advance and retreat with the rotation of the swash plate and each are formed with a hemispherical concave sliding surface, and shoes 5 each formed with a flat end surface part 12 being in sliding contact with the swash plate and a spherical surface part 11 being in sliding contact with the sliding surface 4a of the piston. A cylindrical part 13 is formed between the spherical surface part and the end surface part of the shoe, and the shoe is formed with a flange part 14 that surrounds the boundary portion between the cylindrical part and the end surface part and is in sliding contact with the swash plate. Further, the flange part is located on the inside of an imaginary spherical surface S including the sliding surface of the piston, and the diameter d2 of the cylindrical part is smaller than the diameter d3 of the opening of the sliding surface of the piston. The shoe can be lubricated satisfactorily. |
