PURPOSE:To prevent the deterioration of damping characteristics by removing air bubbles generating in the liquid chamber out of the liquid chamber so that air bubbles may not adversely affect the movement of the liquid in the liquid chamber. CONSTITUTION:A recessed hole opening to the liquid chamber 5 is formed in the bearing hardware 2 at the top of the mount body 1, and a metal mouth piece 10 having an orifice 9 in its center is attached to said opening to make the recessed hole into an absorption chamber 8. Air bubbles generated in the liquid chamber 5 are absorbed in the absorption chamber 8, and by means of the effect of the orifice 9, adverse effects of the absorbed air bubbles are prevented. Therefore, even if air bubbles are generated due to the use over a long period, the deterioration of damping characteristics can be prevented. |
