シール。[Claims for Utility Model Registration] 1. It has a seal ring pressed in the axial direction by a spring, and a mating ring that slides in opposition to this seal ring, one of both rings is supported by the housing, and the other is supported by the rotating shaft. In mechanical seals that rotate together, a squeak member is placed around the outer periphery of the seal ring, and when the seal ring wears out, the squeegee member contacts the housing or mating ring and generates abnormal noise, thereby shortening the seal life. A mechanical seal that is characterized by being designed to notify you when it is about to run out. 2. The mechanical seal according to claim 1,
A mechanical seal characterized in that the squeak member has a notch at the end on the mating ring side.
