ACTIVE VIBRATION CONTROL SUPPORT DEVICE

PROBLEM TO BE SOLVED: To secure a crash stroke by easily breaking a housing when collision load is input to an active vibration control support device. SOLUTION: An actuator case 13 holding the outer peripheral part of an actuator 41 to an upper housing 11 and a lower housing 12 housing an elastic body 19, first and second liquid chambers 30, 31, a movable member 28 and the actuator 41 of the active vibration control support device M is composed of a resin member. The actuator case 13 made of resin is thereby broken easily by impact applied in a collision, and the upper and lower housings 11, 12 can be broken. Consequently, the movement of an engine to a body frame can be made to secure the crash stroke, and moreover the weight of the active vibration control support device M can be reduced in comparison with the case of composing the actuator case 13 of an iron-based member.
