Abstract
There is provided a clutch release bearing in which a water resistance is enhanced. At a side axially opposite from one side where an outer ring rib of a clutch release bearing is formed, there is provided a first seal member externally fitted to an outer ring to be fixed thereto. A seal lip disposed in sliding contact with an outside-diameter surface of an inner ring is formed at a radially-inward distal end of the first seal member. An annular guide is provided at a bearing-outward side of the first seal member, and an axial lip which extends toward the outside of the bearing and extends to be disposed radially outwardly of the guide is formed at a bearing-outward side face of the first seal member. The axial lip is disposed in non-contact, close relation to the guide to form a labyrinth. A radially outwardly-open groove is formed in a joint portion of the axial lip joined to the first seal member.
