PROBLEM TO BE SOLVED: To provide a simply formed and easily installable vibration control damper. SOLUTION: Since a deformation member 12 is twisted and plastically deformed, this damper 10 damps the vibration by the hysteresis damping due to plastical deformation, and develops a stable damping performance. Since a groove part 18 on which a torsional stress is concentrated is formed, even if the deformation member 12 is formed of a single member, the damper can stably develop the damping performance. Since the deformation member 12 can be formed of a single member, it is simple in structure and its installation is facilitated. COPYRIGHT: (C)2008,JPO&INPIT
