PURPOSE:To provide a weather cover having no leakage of rain water or the like and having a universal characteristic to be applied in a pipe and a duct connected to each other by a method wherein a diameter of an extreme end of a flange is made larger than a connection diameter of a fixing plate and a duct inserting inlet is made larger than an outer diameter of the duct. CONSTITUTION:In a weather cover, a position of a fixing plate 22 is determined at a fixing member 20 through which a duct 21 passes in such a way as the duct 21 is passed through a duct insertion port 26, and then a fixing part 23 is fixed by a screw A24. In addition, one end of it is abutted against a fixing plate 22 in such a way as a connection part 31 of the weather cover 29 may be connected to a connection leg 27 and the weather cover 29 is fitted to the fixing plate 22 by a screw B32. Rain water blown through an outer circumference of a gallery 30 of the weather cover 29 is collected at a connection part between the fixing plate 22 and the flange 26 through two-step formation of the flange 26, flowed down from the gallery 30 and thus it will not enter the duct 21. |
