A sealing device characterized in that the fixing member is provided with a foreign matter trapping groove concentric with the sealing. (2) The foreign matter trapping groove according to claim 1 has an inner diameter side opened in the inner circumferential surface of the seal ring, and an outer diameter side extending outward from the outer diameter of the seal ring to form a bag-shaped groove in cross section. Features a sealing device.
