摘要：
An end part of a piston (5) on a front edge side is formed so as to have a crowning of a 1.2-order to 2.5-order curve where a length is 10% or more and 80% or less of a length of a cylindrical part (20) and a height is 10% or more and 160% or less of a clearance. An end part of the piston (5) on a rear edge side is formed so as to have a crowning of a 1.2-order to 2.5-order curve where a length is 10% or more and 60% or less of the length of the cylindrical part (20) and a height is 10% or more and 160% or less of the clearance. An end part of a cylinder block (3) on a front edge side is formed so as to have a crowning of a 1.2-order to 2.5-order curve where a length is 8% or more and 60% or less of the length of a cylindrical part (20) and a height is 12% or more and 125% or less of the clearance.
