リング。A piston ring that is completely fitted into a piston that reciprocates within a cylinder bore, and slides into the bore with the outer circumferential portion protruding from the outer surface of the piston, the portion of the outer circumferential surface facing the combustion chamber. In a thermally sprayed piston ring in which an annular notch is formed all around the ring, a thermally sprayed layer is embedded in this annular notch, and the surface of this thermally sprayed layer is in sliding contact with the bore, the depth of the annular notch is A thermally sprayed piston ring characterized in that the thermally sprayed layer is deepest at a portion close to the crank chamber and becomes shallower toward the combustion chamber so that the thermally sprayed layer does not come into contact with the combustion chamber side wall surface of the ring groove.
