ンジンにおけるピストンリング装置。[Claim for Utility Model Registration] A piston ring is fitted into a ring groove on the outer peripheral surface of the piston, and a corrugated leaf spring is bent into an annular shape between the inner peripheral surface of the piston ring and the bottom surface of the ring groove to form a chevron-shaped portion. In the expander ring, the expander ring has a high chevron portion that is in contact with the inner circumferential surface of the piston ring, and a low chevron portion that is slightly away from the inner circumferential surface of the piston ring. A piston ring device for an engine, characterized in that the piston rings are formed alternately in the circumferential direction.
