Abstract
An active vibration control device includes: a housing; a movable part including at least one movable mass member; an exciting coil that generates a magnetic field with an intensity corresponding to a current supplied to the exciting coil; a magnetic viscoelastic elastomeric member whose viscoelastic property changes in accordance with a magnitude of the magnetic field generated by the exciting coil; and a support member made of a non-magnetic material. The housing and the movable part are elastically connected with each other by both the magnetic viscoelastic elastomeric member and the support member.
