VIBRATION CONTROL DEVICE

PROBLEM TO BE SOLVED: To reduce abnormal noises during input of great vibration. SOLUTION: This liquid-filled vibration control device 1 includes a first mounting member 3 and a second mounting member 4 connected to a vibration generating part or a vibration receiving part, an elastic part 5 elastically connecting the first mounting member 3 to the second mounting member 4, a partition member 8 for partitioning a liquid chamber 7 in the first mounting member 3 into a main liquid chamber 7A and a sub-liquid chamber 7B, and a diaphragm 6 forming a part of the wall face of the sub-liquid chamber 7A. The partition member 8 includes a partition member body 81 supported by the first mounting member 3, a cover 83 mounted on the partition member body 81 at the side of the sub liquid chamber 7B, and a movable member 82 stored in a storage chamber 9 encircled by the cover 83 and the partition member body 81. The cover 83 has a communication hole 87a communicating the sub liquid chamber 7B with the storage chamber 9, and a covered body 10 formed of an elastically-deformable elastic material is covered with a portion around at least the communication hole 87a in the surface of the cover 83 at the side of the sub liquid chamber 7B.
