介装したことを特徴とする制振装置。 A movable mass double-acting hydraulic cylinder is supported on the top of the structure, and a servo valve connects each oil chamber in the hydraulic cylinder to the pump and tank, a controller that controls the servo valve, and a controller that controls the pressure above a certain level. In a vibration damping device that is equipped with a relief valve that drains the hydraulic oil in the raised oil chamber into a tank, and a check valve that supplies the hydraulic oil to the oil chamber whose pressure has become low, the vibration control system extends from the servo valve to each oil chamber of the hydraulic cylinder. A vibration damping device characterized in that normally-closed shutoff valves that are opened by a signal current from the controller are interposed in the middle of the passage closer to the servo valve than the relief valve.
