A bearing unit for a clutch release comprising a sleeve, a support plate, a ring, a bearing and a cover. The sleeve surrounds a motive power shaft and is movable along the shaft. The support plate extends from the sleeve outward in the radial direction of the shaft. The ring has a cylindrically-shaped holding portion fitted with a clutch release bearing and has an axis extending in the axial direction of the shaft and engagement portions with which a clutch releasing fork is engaged as the fork is swung toward the shaft. The bearing, at least the outer race of which is housed in the holding portion so as to have an axis in the axial direction of the shaft, is fitted on the inner circumferential surface of the holding portion so as to be movable in the radial direction of the shaft inside the holding portion. The outer race is pinched at both the end faces thereof between the holding portion and one side of the support plate along the axis of the shaft so that the ring, the bearing and the plate are assembled. The cover covers the outer surface of the holding portion, the outer circumferential surface of the plate and the outer circumferential edge portion of the other side of the plate, and coupling the ring, the bearing and the plate together so that the ring and the plate are unmovable relative to each other in the axial and radial directions of the shaft.
