シール。[Claims for Utility Model Registration] 1. A stationary side consisting of a fixed ring that is axially biased by the biasing force of a spring attached to the outer periphery of a cylindrical casing that is fixed to the fuselage side through a packing and a spring restraining member. a seal body; and a rotary side seal body, which is formed by assembling a rotary ring that slides into contact with the fixed ring via a cup gasket on the outer periphery of a sleeve that is fixed to the periphery of the rotary shaft that is inserted into the body. The sleeve of the rotating side seal body is inserted and fitted into the fitting hole of the casing of the stationary side seal body, and the insertion end of the sleeve is bent into a flare shape and assembled integrally with each other. 1. A mechanical seal which is a unitized mechanical seal, characterized in that a slit is cut in the insertion end of the sleeve. 2. The mechanical seal according to claim 1, wherein a plurality of slits are cut in the insertion end of the sleeve along the axial direction at predetermined intervals in the circumferential direction. 3. The mechanical seal according to claim 1 or 2, wherein the space between each slit at the insertion end of the sleeve is curved into a propeller screw-like vane.
