Abstract:
1. An active vibration isolation support system comprising: an actuator for reciprocally oscillating a movable core on an axis of the actuator by energizing a coil wound in a cylindrical shape; a liquid chamber being disposed on the axis of the actuator, having a volume which varies depending on a load inputted thereto from an outside, and being connected to the movable core, so that an internal pressure of the liquid chamber is controlled; and a bobbin around which the coil is wound, wherein the actuator comprises a yoke, the yoke including: wherein the end surface, only on the liquid chamber side of the coil, is inclined, and wherein a step portion extending in a circumferential direction with respect to the axis is formed on an inner surface of the bobbin, the inner surface being in contact with the inclined end surface of the coil.
