Abstract

PURPOSE: To prevent the fall-off of a seal ring from its holding body and avoid the tilting of the seal ring due to the come-out from its holding body caused when it is assembled.
CONSTITUTION: For instance, at an end of a sealing side 7 in a seal ring holding body 2 at the rotary side, a protrusive part 10 is circumferentially provided as an integral unit. Said protrusive part 10 is partially provided with a slit and formed into a protrusive tip 11. Said protrusive tip 11 serves to press and fix a seal ring 5 to the seal ring holding body 2. Then in the peripheral edge part at the sealing side 7 of the seal ring 5, a tapered face 12 is formed. The protrusive tip 11 is folded and pressed to said tapered face 12. In this way, the protrusive tip 11, by being folded and pressed to the tapered face 12 of the seal ring 5, can press and fix the seal ring 5 to a concave part 2a in the holding body 2. In consequence, the seal ring 5 can be prevented from falling off from the holding body 2.
