ABSTRACT:
A sealing ring assembly comprises a synthetic resin sealing ring body having two opposing stepped cut surface portions including respective planer portions in sliding contact with each other, a synthetic resin gas sealing ring in contact with the inner circumferential surface of the sealing ring body, and a metal ring in contact with the inner circumferential surface of the gas sealing ring. To prevent the stepped cut surface portions from sticking to each other at the planar portions thereof, a metal film layer is provided on a planar portion of one of the stepped cut surface portions.
