PROBLEM TO BE SOLVED: To suppress the generation of curling (transcription) on a film-like member opening/closing an air passage. SOLUTION: The air passage opening/closing device is equipped with the film-like members 16, 22 which are disposed in a case 1a forming the air passage in which blown air flows, and opens/closes the openings 13a, 15a of the air passage, fixing parts 17, 23 fixing one end part of the film-like members 16, 22 to the peripheral edge parts of the opening parts 13a, 15a, winding shafts 18, 24 which are connected to the other end parts of the film-like members 16, 22 and perform the winding and delivering of the film-like members 16, 22, a winding shaft drive mechanisms 19, 25 which move the winding shafts 18, 24 to the direction separating from/approaching to the fixing parts 17, 23 while rotating the winding shafts 18, 24 on the opening parts 13am 15a, and a control means 31 controlling the winding shaft drive mechanisms 19, 25. When the air blowing to the air passage is stopped, the control means 31 operates the winding shaft drive mechanisms 19, 25 to the direction to draw out the film-like members 16, 22.
