PROBLEM TO BE SOLVED: To provide a vibration control device capable of suppressing occurrence of cavitation while simplifying a configuration.SOLUTION: A vibration control device includes: a first attachment member 11 and a second attachment member 12; an elastic body 13 for connecting the first attachment member 11 and the second attachment member 12; a partition member 16 partitioning a liquid chamber 10 into a main liquid chamber 14 and a sub liquid chamber 15, having a recession 47 recessed to the sub liquid chamber 15 side, and having a communication hole 51 communicating an inside of the recession 47 with an inside of the sub liquid chamber 15; a cover member 52 closing the recession 47 from the main liquid chamber 14 side; and an elastic supporting part 53 disposed in the main liquid chamber 14, supporting the cover member 52 to be elastically deformable to a direction separating to the main liquid chamber 14 side with respect to the partition member 16, and opening and closing the recession 47. A connection hole 73 communicating the inside of the recession 47 with the inside of the main liquid chamber 14 is formed in the cover member 52, and a movable part 54 which is displaced in accordance with internal pressure fluctuation of the main liquid chamber 14 and opens and closes the connection hole 73 is stored in the recession 47.SELECTED DRAWING: Figure 1 |
