PURPOSE: A duct structure of a ceiling type air conditioner is provided to enhance assemblability and facilitate the work of wrapping a duct with a heat insulator. CONSTITUTION: A duct structure of a ceiling type air conditioner comprises a discharging duct main body (100) and a discharging duct lid (200). The discharging duct main body is manufactured after a vertically bent line is formed in a rectangular panel and the vertically bent line is folded. An engagement surface is formed on the upper and lower surfaces of the main body. The engagement surface comprises a second bent surface, a third bent surface and a fourth bent surface. The discharging duct lid forms an engagement surface by the edge surfaces being bent at a right angle and the engagement surface is inserted into a coupling hole. |
