description PROBLEM TO BE SOLVED: To carry out a smooth and easy replacement work of a flexible air duct in a construction site and the like and conduct a simple, easy and low cost work of assembly and disassembly of an air duct storage unit in a construction site and the like during a replacement work of a flexible air duct by making a member for mounting the flexible air duct directly thereon to be detachable and to be a component member of easy transportation. SOLUTION: This air duct storage unit is provided with a supporting tube, an air duct holding body for folding and mounting a flexible air duct at a required interval in a longitudinal direction on the outside of the supporting tube, and a flange section for drawing out the air duct so arranged as to be able to draw out the air duct by holding a sufficient tensile force with respect to an extending direction of a folded air duct while gradually expanding and opening a folded air duct. In this case, a bracket 24 is provided to encircle an air duct holding body 10 so as to fix a supporting tube 12 externally on an outer circumference of other end thereof with respect to one end of the supporting tube 12 provided with a flange unit 14 for drawing out the air duct.
