In a vehicular air conditioning apparatus, a first blower unit is connected by a connection duct to a side portion of a casing having respective air passages defined therein, and a second blower unit separate from the first blower unit is connected to a lower portion of the casing. In addition, air is supplied to the interior of the casing from the first blower unit and is cooled by a first cooling section of an evaporator, whereas air that is supplied from the second blower unit is cooled by passing through a second cooling section in the evaporator, which is separated from the first cooling section by a pair of first and second partitioning members.
