Abstract

PURPOSE: To improve the sealing performance of the joint part between a following ring and an elastic bellows by installing the annular bulged part on the holding ring for pushing the contact part between the following ring and the flange of the elastic bellows.
CONSTITUTION: The holding ring 9 for holding the flange 8a of an elastic bellows 8 onto a following ring 4 is formed into nearly U-form in section with a rear member 9a, peripheral member 9b, and a front member 9c. On the rear member 9a, the annular bulged part 10 for pressing the flange 8a of an elastic bellows 8 which contacts with the back end surface 5a of a following ring 5 is formed. As a result of this, the bulged part 10 of the holding ring 9 pushes the flange 8a of the elastic bellows 8 onto the back end surface 5a of the following ring 5 by means of the springy force of the holding ring 9 and the springy force of a spring 7, so that close adhesion force of the joint part between the flange 8a of the elastic bellows 8 and the back end surface 5a of the following ring 5 increases, and the close sealing performance can be increased.
