ル。 It has curved annular inner and outer lips, and a back-up ring made of a low-friction material fitted to the inner periphery of the base where these inner and outer lips join, and which connects the housing and the rotating shaft penetratingly supported therein. In an oil-tight seal that seals between the housing and the rotating shaft by the mutually outward returning forces of the inner and outer lip parts, the inner lip part is attached to the side periphery of the back-up spring. A bearing edge that extends in a tapered manner to an intermediate position is protruded in an annular manner along the rotation axis, and a tip of the bearing edge that contacts the inner surface of the inner lip portion is rounded. Close seal.
