Abstract

PROBLEM TO BE SOLVED: To reduce generation of noise and wear caused by sliding operation of a piston by restricting a minute rotation restricting part with respect to an inner wall of a cylinder block such that it comes into contact with the inner wall at specified point or more when the piston is about to rotate. SOLUTION: A minute rotation restricting part 110 of a piston 10 is composed of a non-contact part 116 and a circular arc part 11. A radius of circle passing through end points P1 , P2 of the part 111 is made equal to or larger than a radium R1 of a cylinder block 20. When it is mode equal thereto, following the rotation of a piston 10 around a center O, the part 111 is brought into face contact with the block 20, while at the time when it is made larger, the part 111 are in contact therewith at two points. With the contact at two or more points, the contact pressure is made low, thereby reducing generation of noise and sliding wear caused by the part striking against the inner wall 20.
