PROBLEM TO BE SOLVED: To damp vibration, while restraining the occurrence of cavitation when inputting large vibration. SOLUTION: This vibration control device includes a cylinder member 3, an installation member 2, a rubber elastic body 4 for elastically connecting the cylinder member 3 and the installation member 2, a liquid chamber 6 formed inside the cylinder member 3 and sealed with liquid, a diaphragm 5 for forming a part of a partition wall of the liquid chamber 6, and a partition member 7 for partitioning the liquid chamber 6 into a main liquid chamber 6A and a sub-liquid chamber 6B and forming an orifice passage 80 for communicating the main liquid chamber 6A with the sub-liquid chamber 6B. A pushing-in member 11 for pushing the diaphragm 5 in the sub-liquid chamber 6B side by interlocking with relative displacement to the cylinder member 3 to the opposite side of the main liquid chamber 6A side of the installation member 2, is arranged on the opposite side of the sub-liquid chamber 6B side of the diaphragm 5, and the pushing-in member 11 is arranged with a clearance between the diaphragm 5 and itself in a state of applying a static load to the cylinder member 3 or the installation member 2.
