ル。 In the above-mentioned rotating shaft side shaft sealing element of the mechanical seal, which airtightly slides and seals the rotating ring carried on the rotating shaft side shaft sealing element and the fixed ring carried on the machine case side shaft sealing element, an annular shape is formed by sheet metal processing. A compression ring has a plurality of claws protruding from the outer periphery of the disk, each bent and protruding from the front and back sides, and the claws protruding from the front serve as rotating ring drive claws to drive the rotating ring. It engages with the notch formed on the back surface in the rotational direction,
In addition, the claw piece protruding from the back side serves as a drive collar engaging claw and engages with a drive notch formed on the outer periphery of the drive collar that is inserted and fixed onto the rotating shaft. A striking tuft of an appropriate size is integrally engaged with an engagement groove formed in the bottom half of the drive notch so as to be slidable in the axial direction, and an elastic pressing force is applied to the rotating ring in the direction of the stationary ring. A mechanical seal comprising a rotary shaft-side shaft sealing element rotatably connected to a rotary shaft.
