PROBLEM TO BE SOLVED: To provide a bearing structure, particularly, a bearing structure with a vibration damping material between a bearing outer ring and a supporting member, for improving the durability of a bearing. SOLUTION: The bearing structure comprises the vibration damping material 2 arranged between a case member and a bearing outer ring portion 1 all over the periphery. The bearing outer ring portion 1 and the vibration damping material 2 have contact with each other at their non-circular faces. Since the bearing outer ring portion 1 and the vibration damping material 2 have contact with each other at their non-circular faces, a pressurized condition such as increased contact pressure is produced by suppressing the rotation of the vibration damping material 2. Thus, friction between the vibration damping material 2 and the bearing outer ring portion 1 is suppressed to improve the durability. COPYRIGHT: (C)2006,JPO&NCIPI
