In a swash plate type compressor in which a shoe (3) is placed between a swash plate (5) and a reciprocal piston (2), the shoe has a convex curved surface (32) having a specific portion extending along an oblate spheroid defined by a predetermined ellipse. The piston has a concave spherical surface (2a) adaptable to the convex curved surface. The specific portion has a ring-like contact portion which is in contact with the concave spherical surface around a minor axis of the predetermined ellipse to surround a portion spaced from the concave spherical surface. In addition, the shoe has a sliding surface (31) slidable along the swash plate. <IMAGE> |
