<P>PROBLEM TO BE SOLVED: To provide a rolling bearing device excellent in vibration damping. <P>SOLUTION: A damping member 2 is disposed so that a part of the inner peripheral surface of the damping member 2 made of a damping material is brought into contact with the outer peripheral surface of the outer ring 6 of a ball bearing 1. A ring axial outer portion 13 positioned on the axial outer side of the axial one end face 19 of the outer ring 6 is formed on the damping member 2. The center axis of the axial outer portion 13 is generally aligned with the center axis of the outer ring 6. Cutouts are formed in the inner peripheral surface of the axial outer portion 13 at a predetermined interval in the circumferential direction of the axial outer portion 13. <P>COPYRIGHT: (C)2008,JPO&INPIT |
