Beschreibung
Zusammenfassung:	A process for producing an oil seal for use in a rotary piston engine, which comprises the steps of forming an inner peripheral surface of an oil seal base body into an angled circumferential surface with a solid angle of 2 theta from a sliding surface side of the body toward a rear surface side or into an indented circumferential surface, cutting out partly the inner peripheral surface on the rear surface side along the inner peripheral surface, plating a hard metal layer on the slant or indented inner circumferential surface, and then honing exclusively a partial zone of the hard layer surface on the sliding surface side.
