PROBLEM TO BE SOLVED: To prevent grease for lubricating a roller clutch from being deteriorated in an early stage caused by mixed with abrasion powder of a clutch holder or exposed to high temperature of the friction heat generated at a slide contact portion. SOLUTION: The clutch cage 28a is formed with a suppression piece 33 in one end of its inside diameter side and a suppression flange 34 in the other end respectively. An engagement portion 35 provided in the tip of the suppression piece 33 and the suppression flange 34 clamp an inner ring 21 for the clutch from the axial both sides. This constitution can restrict the axial displacement of the clutch cage 28a so as to prevent the axial both ends of the clutch cage 28a from slide-contacting with the inside faces of a pair of flanges 27a, 27b comprising an outer ring 25 for the clutch, or a part relatively rotate with the clutch cage 28a. |
