PROBLEM TO BE SOLVED: To provide a vibration control device capable of attenuating even the vibration having a low frequency and a small amplitude without generating noise. SOLUTION: A partition member 24 is arranged, while fitting in an outer cylindrical fitting 14, and a liquid chamber part over the partition member 24 is formed as a main liquid chamber 30, and a liquid chamber part under the partition member 24 is formed as an auxiliary liquid chamber 32. A membrane 25 and a gas chamber 26 opposite to the main liquid chamber 30 through the membrane are arranged in the partition member 24. A valve mechanism 46 is arranged opposite to an opening part of an idle orifice 44 through a diaphragm 28. A selector valve 64 is connected to an expanding/shrinking chamber 35 of the valve mechanism 46 and the gas chamber 26 provided on a back surface side of the membrane 25.
