PURPOSE:To improve the vibration attenuating effect of a rubber bush, by forming hollow chambers on both sides of the center of the bush, i.e., on the side of links and the opposite side, and sealing liquid in the hollow chambers and ports for communicating these hollow chambers. CONSTITUTION:Hollow chambers 19a, 19b are formed in vibration-isolating bush 18 respectively on the side of likns 1, 2 of a bush 11 and the opposite side, and these two chambers 19a, 19b are communicated to each other via connecting ports 20a, 20b. Here, liquid such as grease is sealeed in the hollow chambers 19a, 19b and in the connecting ports 20a, 20b. By making the connecting ports 20a, 20b function as orifices, it is enabled to attenuate axial vibration of links 1, 2 transmitted to an outer sleeve 17. |
