Claims

[Scope of utility model registration request]

A stationary sealing ring fixed to the sealed case and a rotating sealing ring fixed rotatably to the rotary shaft at the same time are brought into sliding contact with each other at their sealing end surfaces, and a sealant is applied to the sealant-coated surface of the sealed case, and the sealing ring is fitted and fixed to the casing. In mechanical seals that
an inclined surface inclined downward in the direction of fitting to the casing on the sealant applied surface of the sealed case;
A sealed case for a mechanical seal, characterized in that a sealant filling annular groove having a substantially serrated cross section is provided with a continuous regulating surface extending radially outward from the deepest part of the inclined surface.
