置。[Claims for Utility Model Registration] Consisting of a slinger that is attached and fixed to a rotating shaft and a device body that is attached and fixed to a housing, the slinger has a sliding surface that is substantially orthogonal to the rotating shaft on the atmospheric side end surface. The device body is provided with a seal lip that makes slidable and sealing contact with the sliding surface, and an annular space surrounded by the seal lip, the slinger, and the outer periphery of the rotating shaft is formed between the slinger and the device body. In the sealing device, a second sliding surface is provided on the slinger at a position farther away from the sliding surface toward the sealing fluid side in the axial direction and on the inner diameter side of the sliding surface, and a second sliding surface is provided on the device main body. A sealing device characterized in that the annular cavity is sealed by providing an auxiliary lip that makes sealing contact with the sliding surface.
