Abstract
A piston includes an engagement portion that engages with a swash plate. The engagement portion is provided with a pair of arm portions and a coupling portion for coupling base ends of the arm portions each other. An axial rib extending in the axial direction is integrally provided in a central part of a back surface of the coupling portion in the width direction orthogonal to a central axis of a head portion of the piston. An accommodation groove is formed on an inner circumferential surface of a cylinder bore corresponding to the axial rib, such that the axial rib does not interfere with the cylinder bore when the piston moves to the top dead center.
