置。[Claims for Utility Model Registration] A pressure ring 5 is fitted into the ring groove 3 of the piston 2, and the outer peripheral edge 5P of the lower surface 5B of the pressure ring 5 is set back inward than the outer peripheral surface 5A of the pressure ring 5. In a pressure ring support device for an engine piston, a relief stepped surface 3c is formed near the outer periphery of the lower surface of the ring groove 3, and the surface width C of the stepped surface 3c is the outer circumferential surface of the lower outer peripheral edge 5P of the pressure ring 5. A pressure ring support device for a piston of an engine, characterized in that the pressure ring support device is set to a dimension equal to or larger than a retraction dimension B with respect to 5A.
