グ。[Claims for Utility Model Registration] (1) A ring groove is provided on the outer periphery of a piston that slides in a cylinder by fluid pressure, and a piston ring formed in an annular shape is fitted into this ring groove. The ring consists of a load part on the inner circumference side and a sliding contact part on the outer circumference side, and a lip is extruded along the circumference on both sides of the load part in the axial direction at the boundary with the sliding contact part. A piston ring characterized by a reduced gap between the piston ring and the ring groove. (2) The piston ring according to claim (1), wherein a pressure receiving part is formed on the outer peripheral side of the lip at a boundary with the sliding contact part.
