A center bearing support suitable for suppressing the decrease in vibration absorbing capability in a high-frequency region is realized.The center bearing support includes an outer ring 3 that has a cylindrical shape and is attached to a member on a vehicle body side in such a manner that an outer peripheral surface 3b thereof is in contact with the member, an inner ring 2 that has a cylindrical shape and is attached to the center bearing in such a manner that an inner peripheral surface 2b thereof is in contact with an outer periphery of the center bearing, and an elastic body 1 that is connected to an inner peripheral surface 3a of the outer ring 3 and an outer peripheral surface 2a of the inner ring 2 and expands in a bellows-like bent shape which is convex toward one direction along the propeller shaft between the inner peripheral surface 3a of the outer ring 3 and the outer peripheral surface 2a of the inner ring 2, wherein the elastic body 1 includes a base part 15 that has a shape of a bent plate and expands in the bellows-like bent shape while maintaining a constant thickness thereof, between the inner peripheral surface 3a of the outer ring 3 and the outer peripheral surface 2a of the inner ring 2, and a convex part 14 that is layered on a convex surface 11a of a bent portion of the base part 15 and protrudes toward one direction, and the base part 15 and the convex part 14 are integrally formed of an elastic material.
