とを特徴とするメカニカルシール。 A mating ring that is airtightly fixed to the rotating shaft side and rotates together with the rotating shaft and a non-rotating seal ring that closely slides are sealed airtightly in an annular recess formed on the housing side through packing and a spring. In the mechanical seal, the mechanical seal has a structure in which the adapter ring is elastically supported and prevented from coming off by an adapter ring fixed to the opening side of the annular recess. and at least one of the notches
A mechanical seal characterized in that the ring has a shape that is the same diameter as the opening edge on the outer diameter side of the annular recess or extends to a larger diameter part than the opening edge.
