WIPO Patent Application WO/2021/251319
Kind Code:
A1
Abstract:
The present invention suppresses the formation of a gap between the inner circumferential surface of a shaft hole and the outer circumferential surface of a seal ring. A sealing structure (1) is for sealing an annular gap between a shaft (50) and a shaft hole (61) into which the shaft (50) is inserted. The sealing structure (1) comprises: a seal ring (2) that has an annular shape around an axis x and that is attached to a groove (51) of the shaft (50); and a lock-engaging section (3) that is formed on a bottom surface (52) of the groove (51) of the shaft (50). The seal ring (2) has a lock section (4) that is formed on an inner circumferential surface (21). The lock section (4) and the lock-engaging section (3) are formed so as to be capable of engaging with each other, and so that when engaged with each other, the seal ring (2) is pressed to the outer circumferential side.
