<P>PROBLEM TO BE SOLVED: To prevent seizure of a flat surface of a shoe and a swash plate, and also seizure of a spherical surface of the shoe and a piston, and to achieve miniaturization of the shoe for a swash plate compressor while maintaining high durability. <P>SOLUTION: The shoe 30 for a swash plate compressor is provided between a swash plate 5 provided obliquely relative to a rotating shaft 2 and rotating together with the rotating shaft 2 and the piston reciprocating in a direction where the rotating shaft extends by rotating the swash plate 5. The shoe 30 of the swash plate compressor is provided with a flat surface 32 abutting on the swash plate 5 and a spherical surface 31 abutting on a hemispherical slide surface 13 formed on the piston. A through hole 35 allowing the flat surface 32 to communicate with the spherical surface 31 is formed between the flat surface 32 and the spherical surface 31. The through hole 35 includes a first cylindrical through hole 36 comprising a first radius d<SB POS="POST">1</SB>and a second through hole 37 comprising a cylindrical shape comprising a second radius d<SB POS="POST">2</SB>larger than the first radius d<SB POS="POST">1</SB>. <P>COPYRIGHT: (C)2012,JPO&INPIT |
