<p><P>PROBLEM TO BE SOLVED: To provide an active vibration control supporting device capable of reducing lateral force generated in a movable core of an actuator. <P>SOLUTION: The active vibration control supporting device M includes a first elastic body 19 receiving the load of a vibrator, a first liquid chamber 30 and a second liquid chamber 31 having at least a part of a wall surface constituted by the first elastic body 19, a driving part (actuator) 41 operated in supply of an electric current in accordance with a vibration state of the vibrator, and a movable member 28 reciprocated by the driving part 41 and varying the volume of the first and the second liquid chambers 30 and 31, wherein the driving part 41 includes an annular yoke 44, a coil 46, the movable core 54B arranged on an inner peripheral side of the yoke 44 so as to be reciprocated and connected to the movable member 28, and a fixed core 42B. The movable core 54B is slidably supported by a cylindrical bearing member 51, and one end of the cylindrical parts of the movable core 54B and the fixed core 42B mutually opposed has a cross section in an almost V shaped recession form, and the other end has a cross section in a wedge shaped protrusion form. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
