PURPOSE: To provide an active operation type vibration suppressing supporting device for a power unit which can develop the effective vibration suppressing effect even for the low frequency vibration such as shaking.
CONSTITUTION: A vibrationproof supporting device is equipped with a vibrating means 14 installed between a car body 12 of a vehicle and a power unit 10, first sensor 16 installed on the power unit, second sensor 20 installed on a suspension member which is shifted by the movement of the wheel 18 of the vehicle, and the third sensor 22 installed 91 at an evaluation point on the car body 12 of the vehicle. Further, a control means which sets each signal of the first sensor 16 and the second sensor 20 as each standard signal and sets the signal supplied from the third sensor 22 as error signal, and properly controls the operation of the vibrating means 14 so that the error signal becomes min.
