Abstract

PURPOSE:To maintain the shape of an air-direction variable vane even in the long-sized vane by composing the vane of internal and external guide plates and rotatably supporting support sections mounted at both ends of the vane and an intermediate support section set up to an intermediate section to the air conditioner body side. CONSTITUTION:Bearings 12 are formed to both side faces 11 of the supply opening 7 of an air conditioner body while a supporter 15 with an intermediate bearing 16 is protruded near the center of the supply opening 7. An air-direction variable vane having an approximately elliptic cross section rotatably supported by these bearings 12, 16 is constituted by combining an external-surface guide plate 19 and an internal- surface guide plate 20, and shafts 13, 13' on side plates 14, 14' incorporated to both ends of the variable vane are born to th bearings 12. An intermediate plate 18 is assembled on the internal-surface guide plate 20 side in the intermediate section of the air-direction variable vane, and an intermediate shaft 17 mounted to the intermediate plate 18 is born to the bearing 16 of the supporter 15. Accordingly, an air-direction variable device having a high air-direction deflection effect is acquired while the intermediate section of the air-direction variable vane is also born, thus preventing the generation of the flexure and deflection of the air-direction variable vane.
