In a clutch release device, a clutch release lever engages one ring of a clutch release bearing, and the bearing ring and release lever are formed to inhibit relative rotation therebetween. For this purpose, the bearing ring may have a polygonal outer surface, in which case the release lever may have parallel flanges between which opposite parallel surfaces of the polygonal section of the bearing ring may be inserted. Alternatively, the release lever may have a wedge shaped portion adapted to engage a braking surface of the bearing ring, formed of a plastic material. In a further modification, the bearing rings have grooves or corrugations in a radially extending surface and adapted to be engaged by one or more projections on the clutch release lever.
