とする円筒面シール。 A non-rotating seal ring which is divided into a plurality of parts in the circumferential direction and which are slid together in a sealed manner and bound together by an extension spring is housed in an annular housing part formed on the inner periphery of the housing, The seal ring is a cylindrical seal in which one of its end surfaces contacts the opposite end surface on the housing side, and the inner circumferential surface slides on the outer circumferential surface of the rotating body. A seal dam part that is in close contact with the outer circumferential surface of the rotating body is formed on the inner circumferential surface, and a pressure guiding surface that is not in contact with the outer circumferential surface of the rotating body and surrounded by the seal dam part and the outer diameter side of the seal ring are formed on the inner circumferential surface. A cylindrical surface seal characterized in that a communication hole connecting the surface is formed in each of the divided bodies.
