。 a liquid chamber formed inside an elastic body provided between a pair of frames, and a partition plate that separates the liquid chamber in a direction in which the pair of frames face each other and is attached to one of the frames; , an orifice that communicates the two liquid chambers separated by the partition plate, a storage chamber in which an opening is formed in the partition plate and communicates the two separated liquid chambers, and the storage chamber includes the a movable plate that is accommodated in a manner that allows slight movement of both separated liquid chambers and that is capable of covering the opening;
Vibration in the low frequency range input between the pair of frames is controlled by the movement of the two separated liquids via the orifice, and vibration in the high frequency range is controlled by the movement of the liquid through the opening. In the liquid-filled vibration isolator, the movable plate is vibrated and damped by moving the movable plate into and out of the storage chamber from the opening. A liquid-filled vibration isolator characterized in that a resonance frequency is set in a frequency range in which vibration is to be suppressed by tuning the diameter of the opening.
