PURPOSE: To improve drainage efficiency of an air cleaning device mounting part by inclining the mounting part gradually downward from the upper reaches part of the mounting opening of a unit case to the lower reaches part reaching a heat exchanger mounting part through the mounting opening, and inclining also the upper face of a case cover in the same direction so as to be inclined continuously. CONSTITUTION: The upper reaches part 13 and lower reaches part 14 of an air cleaning device mounting opening 12 are formed in such a way as to be inclined gradually downward from the inner end part 15 of the upper reaches opening part of a unit case to the mounting part upper reaches end part 16 of an evaporator 7. An outer cover 30 for closing the mounting opening 12 through a seal member formed of an elastic member is formed thick in upper reaches position and thin in the lower reaches position so as to be inclined along the inclination of the upper reaches part 13 and lower reaches part 14 of the mounting opening 12. The tilt angleθ1 of the upper face 31c of an inner cover 31 is smaller than the tilt angleθ2 of the lower reaches part 14 of the mounting opening 12, so that water drops are hardly accumulated in a clearance between the lower reaches side of the inner cover 31 and the end part of the mounting opening 12.
