Abstract

The compression ring 21 is mounted on the seal ring 20 at the end thereof. The compression ring 21 has the outer circumference projections 30 that are fixed in the groove 40 extending in the axial direction at the inner surface of the flange 22 . With this construction, the compression ring 21 can move in the axial direction and is stopped in the rotational direction. The compression ring 21 is pressed by the springs 23. Thus the compression ring 21 works as a stopper to stop the rotation of the seal ring 20 and as a spring receiver.
