PROBLEM TO BE SOLVED: To provide a rolling bearing device which can generate a damping effect as a whole of the device. SOLUTION: The outside diameter of an outer ring 5 is set based on the inside diameter D of a housing 2 in a manner to form a gap part S having a prescribed gap amount h0 extending in the axial direction between the outer peripheral surface of the outer ring 5 and the inner peripheral surface of the housing 2 and length in the axial direction forms B. A protrusion-form spigot part 5b is formed on the outer peripheral surface of the outer ring 5. and the spigot part 5b is situated in the vicinity of a flange part 5a. A coupling portion 5c with the flange part 5a of the outer ring 5 is elastically deformable by cutouts 5e and 5f and displacemant of the outer ring 5 is absorbed through elastic deformation of the portion. The gap part S is filled with oil having predetermined viscosityμ. |
