ABSTRACT:
A liquid-containing type vibration isolating apparatus includes a first restricting passage, which connects a pressure-receiving liquid chamber and a first sub-liquid chamber and which is substantially U-shaped, and a longitudinal second restricting passage, which connects the pressure-receiving liquid chamber and a second sub-liquid chamber and which is provided at a substantially U-shaped inner side of the first restricting passage. The liquid-containing type vibration isolating apparatus can reliably absorb vibration of a wide range of frequencies and requires little space.
