A power unit mounting device for a motor vehicle includes a first plate, a second plate secured to the vehicle body and a bracket member having a flat plate portion which is disposed between the first and second plates. A first active damping actuator is intimately disposed between the first plate and the flat plate portion and a second active damping actuator is intimately disposed between the flat plate portion and the second plate. Each of the first and second active damping actuators selectively expands and contracts in accordance with an electric power applied thereto. Connecting bolts are used for connecting the first and second plates to tighten the first and second active damping actuators therebetween. A controller is employed for controlling the electric power in such a manner that the expanding and contracting vibrations of the first and second active damping actuators are equal in amplitude but different in phase by 180 degrees.
