PURPOSE:To provide a vibration control device for a subframe wherein vibration and noise generated in a body can be reduced without generating a frequency region of large worsening vibration and noise. CONSTITUTION:A supporting part 58 of a subframe 10 is extended in a vehicle longitudinal direction and connected to a body 70 through a connecting part 66 in a vehicle front side and a connecting part 68 in a vehicle rear side. A vibration detector 116 for detecting vibration in a vehicle rear side of the supporting part 58 is provided therein, and in a control circuit, a piezoelectric actuator 94 provided in the vehicle front side of the supporting part 58 is controlled so that the vehicle front side of the supporting part 58 is vibrated in almost a reverse phase against the vibration in the vehicle rear side of the supporting part 58 detected by the vibration detector 116. |
