PROBLEM TO BE SOLVED: To effectively restrain the occurrence of cavitation, without complicating a structure, and without deteriorating damping performance in shake vibration and to prevent generation of an abnormal sound even if cavitation is caused. SOLUTION: In a first installation member 11 of a vibration control device 10, a side surface opening part 17 is formed in a part opposed in the radial direction of the first installation member 11 in a first communicating passage 23 communicating an orifice passage 24 with a main liquid chamber 14, and a second rubber elastic body 29 is arranged for blocking up this side surface opening part 17.
