ール機構。A rotary ring that rotates together with the rotary shaft is closely fitted in the shaft hole to a rotary shaft that protrudes from the inside of the machine body to the outside through a shaft hole, and the outer end surface of the rotary ring and the shaft In a shaft seal mechanism in which a fixing ring that seals the inner peripheral surface of the hole is fixed to the machine body via a stopper,
The stopper is formed into an annular shape that can be fitted into the shaft hole, and is integrally connected to the outer end surface of the fixing ring while being in contact with it, and an axial groove is provided on the outer peripheral surface of the annular stopper, An axial groove is provided in the inner wall of the shaft hole from the position where the annular stopper is fitted to the outside, and the stopper pin is engaged with both grooves at positions where the respective grooves face each other, and the stopper pin is engaged with both grooves at positions where the respective grooves face each other. A shaft seal mechanism characterized in that an annular stopper is fixed by engaging a snap ring so as to make contact therewith.
