<p><P>PROBLEM TO BE SOLVED: To make impact on a swash plate by inertia force of a shoe smaller than that of a former shoe and reduce wear of a surface of the swash plate as compared to the former shoe by inhibiting uneven contact of a flat surface of the shoe on the swash plate. <P>SOLUTION: The shoe 4 comprises a first member 11 including a semispherical surface 4B sliding on a piston 3, and a second member 12 including a flat surface 4A sliding on the swash plate 2, and is formed in a roughly semispherical shape as a whole. An engagement hollow part 11A is formed at a lower surface center part of the first member 11 and an engagement projection part 12A engaging with the engagement hollow part 11A is formed at an upper surface center part of the second member 12. Since the first member 11 and the second member 12 can be mutually separated and oscillated, a lower surface (flat surface 4A) of the second element 12 evenly slides on a slide surface 2A of the swash plate 2 and uneven contact does not occur. Consequently, wear of the swash plate 2 is inhibited as compared to the former shoe. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
