PROBLEM TO BE SOLVED: To provide a vertical duct which can suppress that water is absorbed into the duct.SOLUTION: A vertical duct 20 comprises a duct 22 which extends to a vertical direction, and is opened at its upper end, and a cap 23 attached to the duct 22 at a duct upper end part 22a. The cap 23 has a cap upper end part 23a which is separated from an upper part, and closed from the duct upper end part 22a, and a cap lower end part 23b which is partially fit to the duct upper end part 22a, partially joined thereto, and opened. The cap lower end part 23b has a gutter part 42 extending over the whole periphery of its external peripheral part, and the gutter part 42 has a drainage port 45 at a position in a peripheral direction of a joining part 46 which is joined to the duct upper end part 22a other than a non-joining part which is not joined to the duct upper end part 22a out of the cap lower end part 23b.SELECTED DRAWING: Figure 6
【課題】水がダクト内に吸入されることを抑制できるバーチカルダクトを提供する。【解決手段】バーチカルダクト20は、上下方向に延び、上端が開放されたダクト22と、ダクト上端部22aにダクト22に取り付けられるキャップ23とを備える。キャップ23は、ダクト上端部22aから上方に離間され閉止されたキャップ上端部23aと、ダクト上端部22aに部分的に嵌合され、かつ部分的に接合される開放されたキャップ下端部23bとを有する。キャップ下端部23bは、その外周部の全周に延びる樋部42を有し、樋部42は、キャップ下端部23bのうち、ダクト上端部22aに接合されない非接合部以外の、ダクト上端部22aに接合される接合部46の周方向位置に、排水口45を有する。【選択図】図6
