PROBLEM TO BE SOLVED: To prevent tilting of an armature caused by unbalanced load applied by a movable member of an active vibration isolating support system without employing a bearing. SOLUTION: An active vibration control 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. A shaft 381 of an armature 38 actuated by a coil 34 can move freely along an axis L, and is supported by a pair of upper and lower elastic bodies 44, 47 composed of disk-like carrier plates 51, 52 to suppress vibration in the direction perpendicular to the axis L. Since the elastic bodies 44, 47 are disposed far apart from each other in the axis L direction, a tilt of the shaft 381 of the armature 38 can be minimized even if each of the elastic bodies is displaced to some extent in the directions perpendicular to the axis L. |
