ABSTRACT:
In a shoe 5 for a swash plate compressor, the conical tapered surface 13 is formed between the spherical surface 10 and the rounded edge 14 to converge toward the spherical surface 10 inside an imaginary spherical surface 15 including the spherical surface 10. The conical tapered surface 13 forms a relatively large arcuate gap 23 between the hemispherical concavity 7 and the conical tapered surface 13. The arcuate gap 23 serves to reserve necessary amount of lubricant oil which may be supplied to sliding portions between the spherical surface 10 of the convex surface 11 and hemispherical concavity 7 of the piston 2. In addition, upon manufacture of the shoe 5, it can easily be removed from a metallic mold 52 due to existence of the arcuate gap 23 which prevents tight fit of the shoe 5 in the mold 52.
