CLUTCH RELEASE BEARING

PROBLEM TO BE SOLVED: To provide a clutch release bearing, capable of preventing accumulation of water penetrating into a space part between a seal lip of a seal member and an inner diameter side flange part of an outer ring. SOLUTION: The clutch release bearing is provided with the outer ring 31, an inner ring 50, and a plurality of rolling elements 40. The seal member 60 is disposed between both inner diameter side flange parts 33 and 52 of the inner and the outer rings 31 and 50. The seal member 60 is provided with a core metal 61 having a flange part 63 along one side surface of the inner diameter side flange part 52 of the inner ring 50, and the seal lip 65 projected from the flange part 63 of the core metal 61 to be capable of getting in slide contact with one side surface of the inner diameter side flange part 33 of the outer ring 31. On the flange part 63 of the core metal 61, seal projection pieces 66 are formed to compose a noncontact seal part through a microgap on an inner diameter surface of the inner diameter side flange part 33 of the outer ring 31.
