ダ。[Claim for Utility Model Registration] A combination oil that urges a pair of side rails that are stored in an oil ring groove provided on the outer periphery of the piston and slide on the cylinder wall in the radial outward direction of the piston and in the vertical direction of the piston. A ring spacer expander includes an inclined part that comes into contact with the inner circumferential surface of the side rail and urges the side rail outward in the piston radial direction and in the piston up-down direction, and an oil ring groove continuous to the inclined part. A spacer expander characterized in that a flat part with a notch is formed on the bottom side.
