PROBLEM TO BE SOLVED: To effectively absorb and suppress high frequency vibration, etc., acting diametrically by providing a clearance spece part having a specified diametrical clearance on the outer peripheral part of a rubber-like elastic body connecting one mounting part to the other mounting part. SOLUTION: One mounting part 1 provided with a center boss 2 and the other mounting part 3 are connected through a rubber-like elastic body 7. All over the outer peripheral part of the elastic body 7, a clearance space part 15 having a specified diametrical clearance and depth, is provided. For example, one mounting part 1 is connected to the cabin side, and the other mounting part 3 is connected to the car-body side to vibration-proof support a cabin. When a high frequency vibration is diametrically applied to the mount, the elastic body resolates in response to the amplitude of the vibration in a range of a clearance (c') of the clearance space part 15 to cancel the vibration. When vibration larger than the clearance (c') of the clearance space part 15 is applied to the amplitude diametrically, the elastic body 7 allows the clearance space part 15 to temporarily disappear on a part of its circumference, and abuts on a stopper part 17 to suppress its displacement smaller. |
