カルシール。 A dynamic cylindrical seal surface formed by the circumferential surface of the shaft and a seal ring fitted over the circumferential surface with a small gap therebetween, and a seal housing that prevents rotation of the seal ring. A mechanical seal in which the static seal surface is formed by pressing the end surface of the seal ring into contact with the inner edge of the seal housing by pressing the end surface of the seal ring against the inner edge of the seal housing. A mechanical seal characterized in that it has a structure having an annular tapered gap having a wedge-shaped cross section that widens at an appropriate angle.
