<P>PROBLEM TO BE SOLVED: To provide a fluid-filled vibration isolating device having a novel structure capable of effectively reducing or preventing occurrence of noise caused by cavitation. <P>SOLUTION: A partition member 44 includes a first partition member 46 positioned at a balancing chamber 66 side and a second partition member 48 positioned at a pressure-receiving chamber 64 side. The first partition member 46 is supported by a second mounting member 14 and the second partition member 48 is superposed on the first partition member 46 in such a state that relative displacement toward the pressure-receiving chamber 64 side is allowed. The second partition member 48 is biased toward the first partition member 46 side by pressing a body rubber elastic body 16 to the outer circumferential part of the second partition member 48; and biasing force acting on the second partition member 48 is released by elastic deformation of the body rubber elastic body 16 to allow the second partition member 48 to separate and displace from the first partition member 46, which forms a short circuit passage 76 that communicates the pressure-receiving chamber 64 and the balancing chamber 66 with each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
