ABSTRACT:
A vibration isolating apparatus is disclosed which comprises an inner tube and an outer tube disposed in a parallel axis state to each other and an elastic member stretched therebetween, the elastic member being provided with a pair of liquid chambers disposed in the interior thereof at opposite sides through the inner tube. These liquid chambers communicate with each other through a restricted passage. The elastic member is provided with a pair of cavities on opposite outer sides of the inner tube. The cavities absorb relative displacement between the inner tube and the outer tube. When an amount of absorption becomes a predetermined amount, a compressing force is applied to the liquid chambers.
