PROBLEM TO BE SOLVED: To provide a block type center bearing support having a block-like rubber elastic body showing a superior followability to an axial motion of a propeller shaft and capable of improving durability against a substantial displacement input.SOLUTION: There are provided a plurality of bores acting as spaces axially passing through a rubber elastic body around a shaft hole. The bores are comprised of a combination of inner circumferential bores arranged relatively near the shaft hole and outer circumferential bores arranged relatively far from the shaft hole. The inner circumferential bores and the outer circumferential bores are arranged alternatively on a circumference, and they are partially overlapped on the circumference and have connecting parts formed of a part of the rubber elastic body that are provided among the inner circumferential bores and the outer circumferential bores. The connecting parts are extended to incline against both circumferential direction and a direction perpendicular to the shaft. |
