PURPOSE:To control a decrease in air volume discharged from a selected discharge opening by shifting a membraneous member provided with an opening for opening at least one of plural discharge openings so as to open or close discharge openings except one. CONSTITUTION:A discharge opening switch mechanism 11 for supplying air to each area inside a vehicle is set on the downstream side of a ventilation duct in an air conditioner. And the discharge opening switch mechanism 11 opens each of discharge openings 13-15 for a defroster, a center ventilation, and a heater on each side of a case 12, and also a film damper 23 with each opening 25-27 corresponding respectively to each discharge opening 13-15 provided in the case 12 in a freely slidable state. And the film damper 23 is connected to a drive shaft 31 via a drive arm 30. Furthermore, a switch plate 33 for opening or closing a side ventilation discharge opening 16 according to rotation of the drive arm 30, is formed integrally with the drive arm 30. |
