PROBLEM TO BE SOLVED: To suppress the centrifugal whirling of a propeller shaft caused by resonance.SOLUTION: In a center bearing support 1 in which an inner ring 12 attached to an external peripheral face of a propeller shaft 3 and holding a center bearing 4 is arranged at an internal periphery of an outer ring 11 fixed to a vehicle body side via an annular elastic support member 14 which is composed of a rubbery elastic material, and protrusively bent to a front side of a vehicle, the elastic support member 14 has resonance frequencies which are different from one another in a circumferential direction by having a plurality of relatively-thick wall parts 141 and relatively-thin wall parts 142 alternately in the circumferential direction.SELECTED DRAWING: Figure 2 |
