an air-conditioning case defining an air passage for an air to be blown into the vehicle cabin;
a blower housed in the air-conditioning case; and
a cooling heat exchanger disposed in the air-conditioning case at a position upstream of the blower in an airflow direction, the cooling heat exchanger being configured to cool the air to be blown into the vehicle cabin, wherein
the blower includes a rotational shaft and a suction opening through which the air is sucked into the blower in an axial direction of the rotational shaft, the suction opening facing the cooling heat exchanger in the axial direction,
the cooling heat exchanger includes a facing portion that overlaps with the suction opening in the axial direction and a non-facing portion that does not overlap with the suction opening in the axial direction,
the facing portion is surrounded by the non-facing portion,
the air-conditioning case includes a projected region that is virtually formed by projecting the facing portion toward an upstream side of the air-conditioning case along the axial direction,
the air-conditioning case defines a plurality of introducing openings at positions outside of the projected region, and
at least a first one of the plurality of introducing openings is located on a side of the projected region opposite to at least a second one of the plurality of introducing openings that is other than the at least the first one of the plurality of introducing openings.
