ABSTRACT:
A liquid-filled vibration isolating device comprises a central member, an outer sleeve, an elastic member interposed between the central member and the outer sleeve, at least two liquid chambers defined among them and filled with a liquid, a restricted passage communicating the liquid chambers with each other and a stopper protruding from the central member toward the liquid chamber. In this device, a through-hole is arranged so as to open to the liquid chambers through the stoppers, and a vibration member is disposed in the through-hole, whereby high frequency, small amplitude vibrations can sufficiently be absorbed in addition to the effective damping of low frequency, large amplitude vibrations.
