PURPOSE:To enable air flow passages of large capacity to be formed in a small space at a ventilation duct used for an air conditioner by dividing the inside of a hollow duct main body into a plurality of independent air flow passages and making the ratio of the capacity of each air flow passage changeable by means of a partitioning member. CONSTITUTION:A duct main body is made by making a defroster duct 109 and a side nozzle duct 111 common at a 112 portion, and this duct main body 112 is formed by piling opening portions 113, 114 provided at each of respective ducts 109, 111. A partitioning member 115 is interposed between both opening portions 113, 114, and respective air flow passages 117, 118 are formed by means of this partitioning member 115 and respective ducts 109, 111. And at a vent or bi-level mode, air is made to flow at the duct 111 alone, while at a defroster or heat def mode, air is made to flow at the duct 109 alone, and an arrangement is made so that a predetermined air conditioning operation including a de- blurring treatment operation may be made to be executed. |
