Claims

[Scope of Claim for Utility Model Registration] (1) A floating sheet supported on a rotating side member that is externally fixed to the shaft side, and a seal ring supported on a fixed side member that is fixedly installed on the housing side,
An axial engagement means is constructed between the rotating side member and the stationary side member so that both sliding surfaces are brought into close contact with each other with an appropriate pressing force, and the engagement means is configured by attaching the mechanical seal. A mechanical seal characterized by a structure that allows release. (2) An engagement configured such that the engagement means engages by being inserted into the sleeve of the rotating side member and the outer cylinder of the stationary side member in the axial direction and engaged by being displaced in the circumferential direction. The mechanical seal according to claim 1, characterized in that the mechanical seal comprises an elastic biasing structure for elastically pressing the protrusion, the engaging edge, and the seal ring toward the floating seat.
