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