Claims

[Scope of utility model registration request]

A base consists of a vertical rail fixed horizontally on the building, with reaction support parts protruding from the front and rear ends of each, and a roller in the center of the vertical rail that allows the vertical rail to slide freely in the vertical direction. A closed loop is formed through the movable weight mounted above, a restoring spring attached between the movable weight and the reaction force support part, and the front pulley and rear pulley, which will be described later, through the movable weight. the actuator, which is fixed to the base and pivotally supports the front pulley and the rear pulley; and a braking means that restricts free rotation of both the pulleys. Vibration damping device for buildings.
