PROBLEM TO BE SOLVED: To increase the shock absorbing action of a rubber stopper by alternately moving oil filled in main and sub-liquid chambers as spaces formed inside the rubber stopper between the main liquid chamber and the sub-liquid chamber according to vibration. SOLUTION: At automobile traveling time, when impactive vibration is applied to a chassis frame, oil filled in the main liquid chamber 5 side is discharged to the sub-liquid chamber 6 side through an oil passage by compressive force at violent vibration time of a vehicle. Therefore, the impactive vibration applied to the main liquid chamber 5 side of a rubber stopper 4 is absorbed and relieved. On the other hand, when the impactive vibration is applied to the sub-liquid chamber 6 side housing the oil discharged from a main liquid chamber 5, to the contrary, the oil filled in a sub-liquid chamber 6 flows in the main liquid chamber 5 side through the oil passage formed in a connecting passage 7 and a damping plate of a damping valve 8. Therefore, similarly, the shock absorbing action of the sub-liquid chamber 6 increases. In this way, since the oil filled in the main liquid chamber 5 and the sub liquid chamber 6 is repeatedly moved and replaced, the impactive vibration can be completely vanished. |
