摘要：
In a swash plate type compressor in which a shoe (3) is interposed between a swash plate (5) and a reciprocally movable piston (2), a concave curved surface (21a) is made at an end of the piston to have an elliptical portion with an elliptical shape in cross section. The shoe has a convex spherical surface inserted into the concave curved surface and reciprocally moves the piston in accordance with a rotation of the swash plate.
