It consists of a sealing member and an annular sleeve member attached to the outer member, the sealing member has a sealing lip that extends at an angle so that the diameter becomes larger toward the object to be sealed in the axial direction, and the sleeve member The inner periphery has a sealing surface with which the sealing lip comes into slidable and sealing contact, and the sealing surface is also configured as a tapered surface whose diameter increases toward the object to be sealed in the axial direction. A sealing device with a shake-off function. (2) The sealing device with a swing-off function according to claim 1, further comprising a swing-off lip that extends radially inside the seal lip so that its diameter increases in the axial direction toward the object to be sealed.
