PURPOSE:To make it possible to adjust the positional relationship between a main body and a duct easily even under a condition wherein the position of a duct is determined by a method wherein to an adapter which is made of a cylindrical shaped sheet metal or resin, and is attached to a main body, a flange part is equipped, and on the flange part, cross shaped screw holes which are formed into a cross shape are provided. CONSTITUTION:At several spots on the periphery of a flange part 7 of an adapter 5 which is made of a sheet metal or resin, cross shaped screw holes 13 which are formed into a cross shape are provided so that moving of the adapter 5 is available in a considerably wide range, and the adapter 5 is fixed by fixing screws 14. When a cut part on a ceiling surface 9, which is previously determined, and the position of a suspended main body 1 are different, suspending bolts 3 and a duct 4 are adjusted. When the duct 4 cannot be moved, the fixing screws 14 for the adapter 5 are loosened, and the position of the adapter 5 is moved and adjusted to the duct 4, and the adapter 5 is fixed again by the fixing screws 14. Thus, it is constituted to connect a duct by making it possible to move an adapter by providing cross shaped screw holes, and therefore, it is not required to redo a duct installation, and construction work becomes much easier. |
