Claims

[Scope of utility model registration request]

The sealing device is fitted between relatively rotating members, and includes a seal ring having a tapered surface on the outer circumference and a sealing surface on the outer side of one end, and a sealing device fitted between members that rotate relatively. A pair of sealing members on a stationary side and a rotating side each having a load ring made of an elastic material fitted between tapered surfaces formed on the inner periphery of an edge of a member facing each other and sealed by relative rotation. In the floating seal according to the present invention, a main body portion having an elliptical cross section in which the load link contacts a tapered surface of a seal ring;
It consists of an inner circumferential tapered surface of the relative rotation member and a tongue-shaped portion that contacts a curved surface extending to the tapered surface,
The tongue-shaped portion compresses the main body portion as a reaction force against external pressure, and causes the main body portion to rotate outwardly, thereby holding the load ring in a proper position. floating seal.
