ことを特徴とするメカニカルシール。 A mating ring is tightly fitted to the outer periphery of the rotating shaft inserted into the housing at the axially outer side of the housing and rotates integrally with the rotating shaft; a non-rotating seal ring that is biased axially outward and slides in opposition to the mating ring; and an elastomer diaphragm that is installed to cover a space outside the spring and closes between the housing and the seal ring. The mechanical seal includes a support member that is fixed to one of the housing and the seal ring, is loosely fitted to the other, and extends to cover the side of the elastomer diaphragm opposite to the sealed space. Features mechanical seal.
