<p>An indoor unit (1) is provided with: a drainage passage (34) that forms a first space through which water inside an air conditioning case (2), which has dropped from a source opening section (32), flows down, and communicates with a drain port (3a); and an upright wall section (33) and a hanging wall section (43) that constitute a partition wall separating the drainage passage and a second space (44), which is adjacent to the drainage passage, in such a manner that the water that has dropped into the drainage passage does not flow into the second space. Prevention walls (37, 47, 50), which extend upward from a bottom wall, are disposed inside the second space, and the upper ends of the prevention walls are higher than the position of a fitting section (20) where a first case member (3) and a second case member (4) fit together. According to this configuration, water inside the air-conditioning case can be discharged to the outside from the drain port, which communicates with one of the drainage passages, and water leakages from the fitting area of the plurality of case members can be prevented.</p> |
