摘要： A vehicle-use air conditioning device that supplies air to a side vent aperture portion regardless of a discharge mode, and allows a discharge of air from a defrost aperture portion when a discharge mode that maximizes a ratio of air blown to a passage communicating with a foot aperture portion is employed, is such that a change in an amount of air supplied from the defrost aperture portion is restricted using a simple structure that does not necessitate fine adjustment, even when an air passage on a downstream side of the side vent aperture portion is closed. A passage (a third passage 23) communicating with a side vent aperture portion 17b to a downstream side of heat exchangers 6, 7 is configured of a passage that, when a rotary type first door 25 that adjusts ratios of air blown to a first passage 21 communicating with a foot aperture portion 18 and a second passage 22 communicating with a defrost aperture portion 16 and a center vent aperture portion 17a is in a discharge mode position that maximizes the ratio of air blown to the first passage 21, connects a region to an upstream side of the first door 25 and the side vent aperture portion 17b, regardless of a discharge mode.
