To exert a vibration reducing effect in a wide frequency band based on liquid column resonant action flowing through an orifice passage.

This vibration control device involves a first diaphragm 5 partitioning a main liquid chamber 42 into a first main liquid chamber 42a and a second main liquid chamber 42b so as to be disposed on both sides in the radial direction, a second diaphragm 6 partitioning an auxiliary liquid chamber 43 into a first auxiliary liquid chamber 43a and a second auxiliary liquid chamber 43b so as to be disposed on both sides in the radial direction, and an orifice forming member 7 which retains the first and second diaphragms 5, 6, is mounted on the outer periphery of a rubber elastic body 3, and forms a first orifice passage 75 communicating the first main liquid chamber 42a and the first auxiliary liquid chamber 43a to each other and a second orifice passage 76 communicating the second main liquid chamber 42b and the second auxiliary liquid chamber 43b to each other, and a resonance frequency of liquid L flowing through the first orifice passage 75 and that of the liquid L flowing through the second orifice passage 76 are set so as to be different from each other when vibration is inputted.
