A vehicular air conditioner including: a cooling heat exchanger having a seal member attached on a side face thereof; a case having an air passage therein, the case including a case body provided with an opening through which the cooling heat exchanger is removably inserted into the case body, a cover covering the opening of the case body; and an interior pipe disposed in the case and connected to the cooling heat exchanger. The cover has a substantially U-shaped portion formed with a pair of ribs. The pair of ribs of the U-shaped portion are abut on the seal member on the cooling heat exchanger such that the U-shaped portion and the seal member define a tubular passage. An upper portion of the tubular passage accommodates the interior pipes therein. A lower end opening of the tubular passage communicates with a drain space between a lower surface of the heat exchanger and a drain recess formed at the bottom of the case body.
