周方向に係合させてなるメカニカルシール。 A seal ring is provided on the inner periphery of the housing on the stationary side and is engaged in the circumferential direction by an engaging part, and a seal ring is provided in a state that is engaged in the circumferential direction with the collar on the rotating side that is axially opposed to this seal ring and is engaged in the circumferential direction by the engaging part. A mechanical seal having a mating ring provided in a state in which the seal ring has a step portion formed facing the rear on an outer circumferential surface of the seal ring, and a step portion formed on an inner circumferential surface of the housing facing the step portion of the seal ring. O-rings are interposed between the outer circumferential surface of the mating ring and a step portion formed facing the rear surface of the mating ring, and a step portion formed on the collar facing the step portion of the mating ring. The inner diameters of the step portions of the seal ring and mating ring are made approximately equal to the seal diameters of the sliding surfaces of both rings, and overhangs extending in the axial direction are formed on the back surface of the collar at equal intervals in the circumferential direction. A mechanical seal in which a set screw whose tip is in pressure contact with the outer peripheral surface of a rotating shaft is screwed onto an overhanging portion, and the overhanging portion is engaged in the circumferential direction with a convex portion provided on the rotating shaft.
