PROBLEM TO BE SOLVED: To provide a clutch release bearing having improved water resistance. SOLUTION: On the axially opposite side to one side of the clutch release bearing 10 where an outer ring collar portion 22 is formed, a first seal member 40 is arranged which is externally fitted and fixed to an outer ring 20. At the radially inward front end of the first seal member 40, a seal lip 44 is formed which has slide contact with an outer diameter face 32 of an inner ring 30. An annular guide 50 is arranged on the bearing outward side of the first seal member 40. On the axial outward side face of the first seal member 40, an axial lip 46 is formed extending toward the bearing outward side up to the radial outward side of a guide 50. The axial lip 46 is being located adjacent to the guide 50 in no contact therewith to form a labyrinth. In a root portion of the axial lip 46 on the first seal member 40, a groove 47 is formed which is opened to the radial outward side. COPYRIGHT: (C)2010,JPO&INPIT
