Patent ID: 8616535

Claim:
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: a cylindrical portion facing an inner peripheral surface of the coil; a flange portion facing an end surface, on the liquid chamber side, of the coil; and an inner inclined surface formed in an inner side of the yoke at an intersection of the cylindrical portion and the flange portion, the inner inclined surface being inclined in such a manner that an outer side thereof in a radial direction with respect to the axis comes closer to the liquid chamber than an inner side thereof in a radial direction with respect to the axis, 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.
