PURPOSE:To condition freely from cool wind to warm wind, by arranging a hot wind bypass duct in the downstream of an air mix guide and coupling a cool wind bypass through a secondary air mix damper to a bypass duct coupled with a center duct. CONSTITUTION:A warm wind bypass duct 14 is arranged in the downstream of an air mix guide 7, and a cool wind bypass duct 10 is coupled to one end 9b of a bypass duct 9 coupled with a center duct 11. A secondary mix air damper 16 being operated by an independent a warm wind mix lever 17 is fixed to a branch point thereof. When the warm wind mix lever 17 is operated in the direction A or B, in such an arrangement, preferable temperature control can be made by opening/closing the secondary air mix lever 16 selectively, resulting in the improvement of comfortability. |
