A vibration isolating apparatus wherein an inner tube and an outer tube are disposed coaxially or axially parallel with each other, and a pair of liquid chambers are formed in a vibration absorbing resilient member disposed between the inner and outer tubes. The liquid chambers are communicated with each other through a limiting passage. Each of the liquid chambers is divided by a partition having a flow passage, and one wall of each liquid chamber is defined by a flexible membrane which is capable of expanding and contracting the liquid chamber. Accordingly, low-frequency vibrations of relatively large amplitude are damped by virtue of the limiting passage. When high-frequency vibrations of relatively small amplitude occur, the flexible membranes are deformed in response to the rise and fall in internal pressure in the liquid chambers, causing liquid-column resonance to occur at each flow passage, and thus allowing the dynamic scale factor to be lowered.
