ール。 A mating ring is fixed via a cylindrical buffer rubber to the fitting concave ring of the housing of the machine body through which the rotating shaft is inserted, and a seal ring fixed to the rotating shaft side is attached to this mating ring with a coil spring. The mechanical seal is formed by being pressed and biased by a biasing force to slide into contact with each other and seal the shaft, characterized in that protrusions are provided on both the inner and outer circumferential surfaces of the cylindrical buffer rubber so as to be positioned relative to each other. mechanical seal.
