カニカルシール。 A U-shaped annular seal case is fitted on the inner wall side of the casing into which the rotating shaft is inserted, and the seal ring housed in this seal case is elastically attached to the seal ring provided on the outer periphery of the rotating shaft from the axial direction. In the mechanical seal in which torque is transmitted between the seal case side and the seal ring by abutting the seal ring, an L-shaped ring made of an elastic material is fitted into the seal case, and the L-shaped ring is fitted at multiple locations in the circumferential direction of the seal case. A boss part that engages in the engagement groove of the seal ring is integrally formed in each of the parts, and a protrusion for preventing the seal ring from coming off that protrudes radially inward is connected to the liquid contact side end of the L-shaped ring. Features mechanical seal.
