A ceiling air passage system for a vehicle air conditioner has an air passage into which conditioned air from an air conditioning unit is introduced, a three-dimension structure member having a three-dimension passage shape. The air passage is provided along a vehicle ceiling portion, and the three-dimension structure member is disposed substantially in an entire area of the air passage. Further, a passage member for defining a lower part of the air passage is provided with innumerable air outlets from which conditioned air in the air passage is blown downward in the passenger compartment. Accordingly, the conditioned air can be relatively uniformly blown in a wide area of the vehicle ceiling portion.
