Zusammenfassung:PROBLEM TO BE SOLVED: To prevent a drainage hole from being blocked by growth of ice due to freezing without an increase in bore diameter of the drainage hole.SOLUTION: In an outdoor unit of an air conditioner provided with a drainage hole 21 at a bottom plate 2, the drainage hole 21 has a flange 22 projecting toward an outside of a housing in the peripheral edge part thereof preferably by burring. A tip part 22a of the flange 22 has a diameter enlarged so as to become a diameter φ2 larger than a bore diameter φ1 of the drainage hole.SELECTED DRAWING: Figure 2 【課題】排水孔の孔径を大きくすることなく、結氷による氷の成長により排水孔が塞がれないようにする。【解決手段】底板２に排水孔２１が設けられている空気調和機の室外機において、排水孔２１は、好ましくはバーリング加工により、その周縁部に筐体の外側に向けて突出されたフランジ２２を有し、フランジ２２の先端部２２ａが排水孔の孔径φ１よりも大径φ２となるように拡径された構成とする。【選択図】図２
