Abstract
A torque rod (1) has two elastic bushes (2, 3) to be mounted respectively to a vibration-generating side and a vibration-receiving side, and a connecting rod (4) connecting the two elastic bushes (2, 3). The actively controlled vibration cancellation means (5) is an actuator including: the shaft (5a) having two opposite ends mounted to the connecting rod (4) and extending in an axial direction of the connecting rod (4), the mass member (5b) shaped in a tube to surround the shaft (5a); a coil (5e) and a winding core (5f) fixed to the shaft (5a) in the tube-shaped mass member (5b); a permanent magnet (5d) mounted to an inner peripheral surface of the tube-shaped mass member (5b) or the shaft (5a), and a connecting member (5c) for connecting at least one end of the tube-shaped mass members (5b) to the shaft (5a).
