Abstract
A sealing device designed to minimize accumulation of a fluid medium trapped therein to thereby increase a sealing performance and adapted to seal a space between inner and outer peripheral members rotatable relative to each other. The sealing device includes a generally L-sectioned annular sealing plate fitted to one of the inner and outer peripheral members and a generally L-sectioned annular sealing element fitted to the other of the inner and outer peripheral members so as to confront the sealing plate. The sealing plate has a radial wall and a tilted wall extending from the radial wall so as to incline inwardly thereof, and the sealing element includes a generally L-sectioned base plate provided with an elastic member. The elastic member has a side lip slidably engageable with the radial wall of the sealing plate and a radial lip slidingly engageable with a cylindrical sleeve of the sealing plate.
