シール。A rotating ring is provided on the rotating shaft, or a sleeve shaft that is fitted and fixed to the rotating shaft, and is fitted so as to be slidable in the axial direction.
A gasket such as an O-ring is interposed in a space formed from one end of the inner circumference of the rotating ring for sealing, and a seal ring on the other end of the rotating ring is brought into sliding contact with the stationary ring to form a shaft-sealing end surface. The mechanical seal is characterized in that a protrusion that protrudes into the space is formed on the circumferential surface of the rotating shaft or the sleeve shaft, and the protrusion can prevent the packing from leaving the space. mechanical seal.
