に構成したことを特徴とするダンパー。[Claims for Utility Model Registration] A frame body formed into a rectangular tube shape with both ends open and mounting flanges protruding from the periphery of both ends, and any number of on-off valve plates comprising a blade plate attached to the rotating shaft. In the damper, the on-off valve plates are rotatably arranged in parallel in the frame, and the ventilation passages in the frame are opened and closed by rotating the on-off valve plates. A gear is mounted on the protruding end of the rotating shaft of each on-off valve plate, and the gears are meshed with each other. One of the rotating shafts is formed to be longer than the rotating shafts of the other on-off valve plates, and a worm gear is mounted on the end of the rotating shaft. A damper characterized in that the above-mentioned on-off valve plates are rotated in conjunction with each other by rotating a worm detachably attached to the damper by operating a handle.
