PURPOSE: To provide an easily handled air duct housing device having a simple structure and a method for taking out housed air ducts in which the air ducts are housed and held so as to be folded and drawn similarly to a conventional case, the air ducts can be sequentially and smoothly drawn while prescribed tension is held on the air ducts, upon installation of the air ducts and the air ducts can be directly easily connected together without using rings or the like. CONSTITUTION: An air duct housing device comprises an air duct holder for folding and housing flexible air ducts 10 between an inner tube 16 and an outer tube 18 at prescribed intervals in a longitudinal direction and a flange part for drawing the air duct while the air duct folded at one end part of the opening side of the air duct holder is gradually expanded and sufficient tension is maintained relative to its extending direction. |
