A mixing door (5) provided between air ducts (10) and (11) of an automobile air conditioner it extended in a direction of intercepting the air flow supplied from the upstream side air duct (10), and shaped in an arc having a prescribed radius of curvature and curving toward the downstream side of the air flow direction. This door (5) is guided by an arcuate grooved cam (19), and opened and closed vertically by a sliding mechanism (M). It is low in ventilation resistance and can be smoothly operated, with excellent sealing performance and temperature control performance achieved, without sacrificing the compactness of the unit.
