To provide a reed screen-like curtain securing ventilation and daylighting intercepting direct sunlight through a hollow part formed by a cylindrical part of a honeycomb structure and obtaining a screening effect excluding the front side of the hollow part.
A large number of curtain members 10 each formed by connecting a large number of hollow cylindrical parts 13 formed of a flexible sheet material, in a vertically spreadable/foldable manner in one to three layers, are hung between an upper frame 2 and a lower frame 3 liftable by an operating mechanism 4. Each cylindrical part 13 is arranged so that its axis points in a direction orthogonal to a parallel-placed surface of the large number of curtain member 10, and its axial length is 0.5-3 times the breadth of an opening in the folded state of the single cylindrical part.
