Abstract:
Provided is a fluid-filled vibration isolation device with a new structure, which is capable of effectively reducing or preventing pounding noise generated by contact of a movable member.
A hollow buffer (72) provided with an interior space (88) is housed and disposed in a housing space (64), the buffer (72) is in contact with the wall inner surface on the pressure receiving chamber (66) side of the housing space (64) and the wall inner surface on the balancing chamber (68) side thereof, a movable member (92) is housed in the interior space (88) of the buffer (72), the fluid pressure in the pressure receiving chamber (66) is exerted on one surface of the movable member (92) by causing a first window part (78) formed in the buffer (72) to communicate with a first communication hole (44) of the housing space (64), and the fluid pressure in the balancing chamber (68) is exerted on the other surface of the movable member (92) by causing a second window part (80) formed in the buffer (72) to communicate with a second communication hole (60) of the housing space (64).
