Abstract
In a vibration isolating device, a main chamber has a part of a wall constituted by a first elastic member to be deformed by input vibration and is filled with liquid, and a sub chamber has a part of a wall constituted by a second elastic member and is filled with liquid, and the main chamber communicates with the sub chamber through a main flow path. A liquid pressure adjusting plate is installed within the main chamber and divides the main chamber into a first chamber and a second chamber and vibrates in an opposite phase to that of the input vibration. The first chamber communicates with the second chamber through a sub flow path and the dimensions of the sub flow path is set so that the sub flow path is choked during high frequency vibration of the liquid pressure adjusting plate.
