PROBLEM TO BE SOLVED: To provide a vibration control device capable of obtaining a damping effect and a spring lowering effect for not only an input of vertical direction vibration but also an input of a peripheral direction. SOLUTION: This vibration control device is constituted of a cylindrical metal fitting 1, a mounting metal fitting 2, an intermediate cylinder 3 internally fitted into the cylindrical metal fitting 1, an elastic body 4 to connect the mounting metal fitting 2 and the intermediate cylinder 3, a diaphragm 5 to constitute a liquid chamber together with the elastic body 4, a partition member 6 for partitioning the liquid chamber in the vertical direction of the elastic body 4 side and the diaphragm 5 side, and an orifice 7<SB>AB</SB>to communicate the partitioned upper liquid chamber A and lower liquid chamber B. A plurality of peripheral liquid chambers C and D independent in the peripheral direction are provided between the cylindrical metal fitting 1 and the elastic body 4. Preferably, two pairs of the peripheral liquid chambers facing to each other are provided. The one peripheral liquid chamber C<SB>1</SB>on a high rigidity side and the one peripheral liquid chamber D<SB>1</SB>on a lower rigidity side are communicated by an orifice 7<SB>C1D1</SB>. The other peripheral liquid chamber C<SB>2</SB>on the high rigidity side and the other peripheral liquid chamber D<SB>2</SB>on the low rigidity side are communicated by an orifice 7<SB>C2D2</SB>.
