Abstract
This dynamic damper is provided with a movable part that can be moved by external input, and an excitation coil for generating a magnetic field of an intensity corresponding to a supplied electric current. The movable part is configured to include: first and second magnetic cores in which magnetic paths, which are pathways for the magnetic field generated by the excitation coil, are configured as annular closed magnetic paths; and a magnetic viscous elastomer of which the viscous properties change in accordance with the size of the magnetic field generated by the excitation coil. The magnetic viscous elastomer is arranged so as link at least one location in the first and second magnetic cores and constitutes a closed magnetic path.
