PROBLEM TO BE SOLVED: To reduce electric power consumption while maintaining durability of an actuator to actuate a movable member in an active vibration isolating system. SOLUTION: An active vibration isolating support system M to prevent transmission of vibration from an engine E to a body frame F has an electromagnetic actuator 29 to change capacity of a liquid chamber 24 by reciprocating a movable member 20. Since a shaft 38 of an armature 38 actuated by a coil 34 is supported on a bearing 36 such that the axle 381 can move along an axis L, an air gapβcan be minimized and the size of the coils 34 can be reduced. Also, since a connecting rod 39 to connect the movable member 20 with the armature 38 is supported by a coil spring 41 and conical spring 42 such that it can swing with respect to the armature 38, vibration of the movable member 20 is prevented from being transmitted directly to the shaft 381 of the armature 38. As a result, durability of the bearing 36 can be enhanced. |
