Abstract

An air conditioning device includes a casing that provides multiple air passages, a blower fan that suctions an air from the multiple air passages and blows out the air in the casing, a suction side partitioning member that is disposed on a suction side of the blower fan in the casing and separates air flows from the multiple air passages from each other, and a blowing side partitioning member that is disposed on a blowing side of the blower fan in the casing and separates the air flows from the multiple air passages from each other. The suction side partitioning member and the blowing side partitioning member are disposed so that a relative position of the blowing side partitioning member to the suction side partitioning member is deviated in a rotation direction of the blower fan.
