[Problem] To provide a vehicle air-conditioning unit that can effectively prevent fogging of window glass at the left and right sides of a vehicle cabin by increasing the airflow amount of air sent out from a side band aperture when in a foot mode in addition to having increased compactness of the vehicle air-conditioning unit. [Solution] An air duct (3) formed within an air-conditioning case (2) has: a first duct (12) that leads warm airflow to a center band aperture (9), a side band aperture (10), and a defrosting aperture (8); and a second duct (13) that branches from the first duct (12) and leads warm airflow to a foot aperture (11). A first door (15) is disposed at the branching position of the air duct (3) to the second duct (13), and a second door (16) is disposed between the center band aperture (9) and the defrosting aperture (8). When in the foot mode, the first door (15) closes the first duct (12) and opens a first supply duct (22), the first supply duct (22) interconnects the first duct (12) and the second duct (13), the second door (16) closes the center band aperture (9) and forms a second supply duct (29) at the upstream side of the side band aperture (10), and the second supply duct (29) interconnects the side band aperture (10) and the direction of extension of the first supply duct. |
