[Problems to be solved by the device]

 Since the supporting mold member 20 is usually formed of a steel plate having a thickness of 1.6 mm, a fixing member 26 such as a rivet or a tapping screw is used to mount the duct supporting mold member 20 on the duct using the mounting holes 21 and 21. When the fixing member 26 is inserted into the mounting holes 21 and 21 and is fixed by using a tool, it is difficult to erect the fixing member 26 upright at the hole position because the duct supporting mold member 20 is thin. Therefore, not only the workability is poor, but also the duct surface is damaged by tilting the fixing member 26, and the work safety such as contact accident between the tool and the hand when the fixing member 26 is manually placed to stand upright is lacked. There was a problem. It is an object of the present invention to provide a duct supporting mold member in which workability of mounting work is improved by forming the duct supporting mold member in a shape that allows the fixing member to stand upright at the mounting hole position.
