Claims

[Claims for Utility Model Registration] 1. In a mechanical seal, a rotating member is attached to a rotating shaft, with a rotating ring and a stationary ring supported in a floating manner, and an annular sealing ring on the back surface opposite to the sliding surface of the rotating ring. A mechanical seal that is supported in the axial direction by a non-rotating member of the seal housing that houses the mechanical seal with an annular sealing ring on the back surface opposite to the sliding surface of the stationary ring. 2. The floating support of the stationary ring is fitted into the circular hole of the non-rotating member attached to the seal housing, and the stationary ring is fitted into the circular hole of the non-rotating member, and is fixed by being fitted into either one of the stationary ring or the non-rotating member, and by a pin which is loosely fitted into the other. The rotating ring is loosely fitted into the circular hole of the rotating member which is prevented from rotating and the floating support of the rotating ring is fixed to the rotating shaft, and the rotating ring is fitted and fixed into either one of the rotating ring and the rotating member, and is loosely fitted into the other. A mechanical seal according to claim 1, which is prevented from rotating by a pin. 3. The mechanical seal according to claim 1, wherein the mechanical seal device has an intermediate floating ring.
