In a vehicular air conditioning apparatus, a pair of covers are provided on the respective sides of the casing that is constituted by respective air passages. The covers rotatably support a pivot shaft for a defroster damper and a pivot shaft for a sub-defroster damper. The sub-defroster damper is disposed in a passage directly connecting the heater core with the defroster blow-out port, and is disposed on an upstream side of the defroster damper. First and second blower units supply air into the casing. The sub-defroster damper is disposed so as to face a passage which is disposed even inside the casing. Thus, the flowing direction and the amount of air is adjusted.
