Zusammenfassung:PURPOSE: A non-directional smoke control damper is provided to uniformly disperse the air current in a chamber by offering the non-directional characteristics of the damper. CONSTITUTION: A non-directional smoke control damper includes a central blade, outer blades(12), and a blade advancing device. The outer edge of the central blade is overlapped with the edge on openings formed on the outer blades. The outer edge of a prior outer blade is overlapped with the edge on an opening located on another outer blade on the rear side. Supporting shafts(110) penetrate each overlapped portions, and have the rear side penetrating a shaft connecting plate(23). The blade advancing device successively advances the outer blades when the device is advancing the central blade to forward.
