PROBLEM TO BE SOLVED: To prevent the slide faces of a seal ring and the mate member of the seal ring from being abraded by providing an annular member having an engagement fixing means regulating relative movement between a face to be pressed and the seal ring, on the position sandwiched with one of the face to be pressed and the seal ring. SOLUTION: In the mounting process of a bush 4, by caulking the edge of a cut part 4d so as to bite in the surface of a groove 2b in the circumferential direction, the bush 4 with the groove 2b in the circumferential direction is fixed more firmly, and the bush 4 is prevented from moving in the circumferential groove 2. A seal ring 3 is an annular member having rectangular cross section, and it is received in an annular gap among the axial direction part 4a and the flange parts 4b, 4c of the bush 4. It receives pressure from the sealded fluid side P, and it is pressed against the flange part 4c as a face to be pressed, and a shaft hole 1a as the other circumferential wall opposite to the circumferential groove 2b. |
