<p>This dynamic damper device (1) comprises: a damper mass device (60) having a damper mass (61) connected, via an elastic body (30), to the rotary shaft (14) of a power-transmitting device (5) that is capable of changing the speed of rotary power with a main transmission (8) and transmitting the rotary power to the driving wheels (10) of a vehicle (2); and a damper transmission (40) that is provided in the power-transmitting path between the elastic body (30) and the damper mass (61) and that changes the speed of the rotary power transmitted to the damper mass (61) at a speed-change ratio corresponding to the speed-change ratio of the main transmission (8). The dynamic damper device (1) is characterized in that the damper mass device (60) is capable of storing, as inertial energy, the rotary power transmitted to the damper mass (61). Thus, the dynamic damper device (1) has the effect of achieving both vibration reduction and an improvement in fuel-saving performance.</p> |
