PROBLEM TO BE SOLVED: To suppress vibration of a power unit and suppress its transmission to a car body over a wide vibration frequency range. SOLUTION: An elastic member 7 and two fluid chambers 14, 15 which are separated by a damper means 11 are arranged between a movable part 5 installed on a power unit side and a fixing part 6 installed on a car body side. The wall of the fluid chambers 14, 15 is formed as a movable wall 17, and an actuator 21 for moving the movable wall 17 is arranged facing to the movable wall 17. The actuator 21 is installed on a car body member 4, and a load sensor 30 is arranged between the actuator 21 and the car body member 4. A spring member 39 acted in parallel with a load sensor 30 is arranged on the outer peripheral side of the load sensor 30. The actuator 21 is driven on the basis of the signal of the load sensor 30, and the movable wall 17 is actively controlled. |
