Provided is a dynamic damper device (1) characterized by comprising: a planetary gear mechanism (20) that includes a plurality of differentially rotatable rotating elements; an elastic body (31) that couples a rotating shaft (10) which rotates when force is transmitted thereto and a first rotating element (20C) of the planetary gear mechanism (20); and a rotation control device (40) which is connected to a rotating element different from the first rotating element (20C) in the planetary gear mechanism (20), regulates torque that operates on the first rotating element (20C), and controls the rotation of the planetary gear mechanism (20). Accordingly, the dynamic damper device (1) achieves the effect of being able to suitably reduce vibration. |
