PROBLEM TO BE SOLVED: To provide a clutch release bearing preventing inclination when a sleeve slides and preventing occurrence of abnormal noise, by improving the roundness of the inner peripheral surface of the wall thickness portion of the sleeve. SOLUTION: This clutch release bearing CRB includes: the resin sleeve 10 axially slidably supported by a power transmission shaft 61; a flange member 20 having an inside diameter end buried in the sleeve 10, and pushed at an outside diameter end to one side in an axial direction by the release fork 62 of a clutch mechanism; and a bearing portion 30 retained by the sleeve 10 in order to be positioned between the flange member 20 and the diaphragm spring 63 of the clutch mechanism and push-pressing the diaphragm spring 63 in association with the sliding of the sleeve 10 to the one side in the axial direction. The sleeve 10 is formed with the wall thickness portion 12 for regulating the inclination of the flange member 20 to the other side in the axial direction. The extended wall 42d of the inner portion 42 of a cover 40, as a reinforcing metal fitting, is buried in the wall thickness portion 12. COPYRIGHT: (C)2009,JPO&INPIT
