<p>PURPOSE:To perform a whirl stop between a ring and a joint body to the full by making width of an inner circumferential surface wider than a bottom surface of an peripheral groove but narrower than width of an opening of the peripheral groove, while installing the ring with this peripheral groove on the outer circumferential surface. CONSTITUTION:Width 3a of an inner circumferential surface of a ring 3 is made wider than width 6c of a bottom surface of a peripheral groove 6 of a joint body 1 but narrower than width 6d of an opening of this peripheral groove 6 whereby the ring 3 is made easy to be fitted to the peripheral groove 6 of the joint body 1. When the inner circumferential surface of the ring 3 is installed in the peripheral groove 6 of the joint body 1, an edge of the inner circumferential surface of the ring 3 hits on both taper side walls 6a of the joint body 1 and thereby it is cruched, and since the whole inner circumferential surface of the ring 3 is made to stick close to the peripheral groove 6 of the joint body 1, a whirl stop between the joint body 1 and the ring 3 is performed sufficient enough.</p> |
