ABSTRACT:
A vibration isolator in which an elastic body is stretched between inner and outer tubes connected to a vibration source and a vibration receiving member, respectively, and in which a pair of liquid chambers disposed on opposite sides of the inner tube communicate with each other through a restricted passage, and the vibration isolator has an intermediate tube provided between the inner and outer tubes and supported on the outer tube. The intermediate tube has a portion serving as a partition spaced apart from both the inner and outer tubes. One of the liquid chambers is formed between the partition and the elastic membranous member located outside the partition. Even if the inner and outer tubes are relatively displaced to a large extent, the relative dispalcement therebetween is limited by the contact between side inner and intermediate tubes.
