An outer ring (11) includes an outer ring small-diameter part (11b) extending toward one axial side with respect to the outer ring raceway (11a), a radial wall part (11c) extending from an axial end portion of the outer ring small-diameter part (11b) toward an inner diameter-side, and a folded-back part (11d) extending from a radially inner end portion of the radial wall part (11c) toward the other axial side. The folded-back part (11d) radially overlaps the inner ring small-diameter part (12b) with a radial gap (C1, C2) therebetween. The radial gap (C1) of an inner diameter-side entry formed by an axial end of the folded-back part (11d) and the inner peripheral surface of the inner ring small-diameter part (12b) is smaller than the radial gap (C2) of an inner diameter-side exit formed by an axial end of the inner ring small-diameter part (11d) and an outer peripheral surface of the folded-back part (12b). Therefore, it is possible to reduce rotating torque by controlling an oil amount and a flow of lubricant to be supplied to the bearing for a clutch and thus reduce a stirring resistance of the lubricant.
