Abstract:
[Problem] To provide a vehicle air conditioning unit having improved comfort. [Solution] In a vehicle air conditioning unit (20), an auxiliary adjusting unit (65) capable of adjusting a flow rate of blown air by regulating a flow passage area of a lower cold air bypass (By2) is formed on a rotating shaft portion (61) of a lower mix door (60). The auxiliary adjusting unit (65) reduces a flow passage cross-sectional area of the lower cold air bypass (By2) when blown air that has passed through a lower portion of a heater (33) and blown air that has passed through the lower cold air bypass (By2) both flow toward a rear opening portion (44). Preferably, a center vent opening portion (43) is provided on a downstream side of a side vent opening portion (42) as seen along a flow direction of lower conditioned air.
