Claims (1)
つ閉作動時に閉切性能が要求されるダンパにおい
て、前記ダンパ羽根と一体の軸に一端を固定した
回動用のレバーの他端に、前記ダンパ羽根が閉状
態のときに前記レバーに対してピストンロツドが
９０゜に近い状態を維持する如くシリンダ形駆動
装置を凍結配置したことを特徴とするシリンダ形
駆動装置を用いたダンパ。 In a damper in which the blades of the damper rotate 90 degrees to open and close, and in which closing performance is required during the closing operation, the damper is attached to the other end of a rotating lever with one end fixed to a shaft integral with the damper blade. A damper using a cylinder-type drive device, characterized in that the cylinder-type drive device is frozen so that the piston rod maintains a state close to 90 degrees with respect to the lever when the blade is in the closed state.
