Anti-vibration device for vehicle

Abstract

A vehicular antivibration device includes a torque rod and an actuator. The torque rod is connected at a first end to a vehicle body and connected at a second end to a vibration source. The actuator is disposed between the first end and the second end of the torque rod, includes an inertia mass supported on the torque rod, and causes the inertia mass to reciprocate in the axial direction of the torque rod. The actuator includes a coil, a magnetic core, a permanent magnet and a heat-conducting member. The magnetic core forms magnetic paths for the coil, and the coil is wound around the outer periphery of the magnetic core. The permanent magnet faces the inertia mass and is disposed on the magnetic core. The heat-conducting member is disposed so as to contact the coil and the torque rod.
