PROBLEM TO BE SOLVED: To provide a liquid filled vibration absorbing device having reduced size and weight for suppressing the occurrence of separation sounds during large-amplitude vibration input. SOLUTION: With large-amplitude vibration input, a diaphragm 9 is stuck to the reverse face of a first clamping member 17. A through-hole 17b1 is formed passing through a central member 17b of the first clamping member 17. Even when the diaphragm 9 is moved apart from the reverse face of the first clamping member 17 with a direction change of vibration input, liquid pressure in the through-hole 17b1 is raised by moving a membrane 15 so that the diaphragm 9 can be gradually separated from the reverse face of the first clamping member 17. As a result, the occurrence of separation sounds is suppressed. In this way, since the through-hole 17b1 is provided for suppressing the occurrence of the separation sounds, there is no need for a wider space between the reverse face of the first clamping member 17 and the diaphragm 9. Thus, the liquid filled vibration absorbing device 100 has reduced size and weight as a whole, accordingly. COPYRIGHT: (C)2010,JPO&INPIT |
