PROBLEM TO BE SOLVED: To damp vibration in a wide frequency range by increasing a change width of a resonance frequency in a restricting passage, while restraining enlargement. SOLUTION: This liquid-sealed vibration control device 1 includes a cylindrical first installation member 2 connected to any one and a second installation member 3 connected to the other among a vibration generating part and a vibration receiving part, an elastic body 4 for elastically connecting the first and second installation members 2 and 3, and a partition member 5 for partitioning a liquid chamber 6 in the first installation member 2 into a main liquid chamber 7 and a sub-liquid chamber 8, wherein the partition member 5 is formed with the restricting passage 15 for generating liquid column resonance by making liquid in the liquid chamber 6 flow by communicating the main liquid chamber 7 with the sub-liquid chamber 8. The partition member 5 is provided with a moving wall surface 67a for defining the restricting passage 15 and an opposed wall surface 55a opposed to the moving wall surface 67a and defining the restricting passage 15. Among the moving wall surface 67a and the opposed wall surface 55a, at least one is inclined in the moving direction of the moving wall surface 67a. COPYRIGHT: (C)2011,JPO&INPIT |
