Zusammenfassung:PURPOSE:To simplify structure and prevent air leak effectively in a device for opening/closing one air passage part or more. CONSTITUTION:Three air passage parts 5, 6, 7 where air flows through outward from the inside are provided in an air duct 1, and an air passage switching device 8 is provided by combining a film member 10 with a rotary door 9 for opening/closing these air passage parts 5, 6, 7 to switch the air passages. The circular arc face like peripheral wall part 12 of the rotary door 9 is provided with four opening parts, and the outer peripheral surface of the rotary door 9 is provided with the film member 10, formed of a PET film having a vent hole 10a lapped with one opening part, with slight slack. When the rotary door 9 is rotatory-displaced by a control cable 17, the air passage parts 5, 6, 7 lapped with the vent hole 10a are opened, and the other air passage parts 5, 6, 7 are closely sealed by the film member 10 projecting in such a way as to swell by air pressure.
