PURPOSE:To improve a feeling of driving comfortableness and durability in a controller, by driving an actuator with a detecting signal out of a vibration detector, while detecting a driving state, and interconnecting an empty space, where an elastic body exists, to an engine negative pressure part at the time of driving but selecting it to a positive pressure part at the time of stoppage. CONSTITUTION:An engine is discriminated as it is at idling or driving by an engine speed detector while a three-way valve is selected to where it should be, and a negative pressure port 25 is interconnected to a suction pipe at the time of driving and to a positive pressure part at the time of idling, respectively. At driving, an empty space 35 is made to come into suction pressure whereby a pressure differential between these spaces 35 and 36 grow large, pushing up a pressing device 23, and thereby a movable mass body 9 is locked thereto. On the other hand, at idling, the space 35 is interconnected to the positive pressure part, making the pressure differential between these spaces 35 and 36 dwindle away to nothing, whereby the pressing device 23 is pushed up and the body 9 is opened free, thereby making an actuator 6 come into a state of being operated. And, since the body 9 comes to a stationary state at the time of driving, any impact to a casing 18 due to vibrations in the body 9 and disturbance is avoided, thus no noise happens and service life is prolonged. |
