PURPOSE:To surely absorb any vibration of a high frequency by providing a vibration detecting sensor for detecting a vibration transmitted to a vibration receiving part and vibrating a vibration member by means of controlling an actuator for generating an oscillating force so as to reduce an amplitude due to the vibration of the vibration receiving part. CONSTITUTION:This vibration proof device main body 10 is provided with a cup-like lower part attaching base 12, and an annular elastic supporting body 22 is vulcanized and stuck to the inner peripheral surface of the cylindrical part 20B of a supporting metal fitting 20 disposed on the upper side thereof and a cup-like vibration plate 24 is vulcanized and stuck to the inner peripheral surface of the elastic supporting body 22. On the external side of the vibration plate supporting metal fitting 20, an external cylinder 26 is disposed concentrically thereto and a fixing part 30 is provided for supporting a bracket 40 to which an engine is attached via an annular elastic body 28 vulcanized and stuck to the inner periphery thereof. An electromagnet 50 serving as an actuator is attached to the lower part attaching base 12 and thereby an oscillating force is generated so as to reduce an amplitude due to the vibration of a car body 16 detected by means of a vibration sensor 60. |
