PROBLEM TO BE SOLVED: To provide a vibration reduction device capable of increasing an exciting force of an actuator.SOLUTION: A vibration reduction device comprises: a rod connecting an engine to a vehicle body; an actuator causing an inertia mass supported by the rod to make reciprocating motion in a predetermined direction within the rod; and control means controlling the actuator to generate a force in proportion to a speed of a displacement of the rod in the predetermined direction, the actuator includes: a first coil generating a magnetic field by a current from a power supply to cause the inertia mass to make the reciprocating motion; and a second coil generating a magnetic field by a current to cause the inertia mass to make the reciprocating motion, and the first coil and the second coil are connected in parallel.

    【課題】アクチュエータの加振力を増大できる振動低減装置を提供する。【解決手段】エンジンと車体との間を連結するロッドと、ロッドに支持された慣性マスをロッド内で所定方向に往復動させるアクチュエータと、ロッドの所定方向への変位の速度に比例した力を発生させるようアクチュエータを制御する制御手段とを備え、アクチュエータは、電源からの電流により磁界を発生させて、慣性マスを往復動させる第1コイルと、電流により磁界を発生させて、慣性マスを往復動させる第2コイルとを有し、第1コイル及び第2コイルは並列に接続されている。【選択図】 図2
