Abstract

PURPOSE:To simplify the structure and to improve productivity of the fan impeller in the caption by making a boss from a part of a hub with a surface perpendicularly intersecting a drive shaft passed through by the boss, and a hollow box. CONSTITUTION:An impeller 1 is composed of a sheet steel hub 2, the hub 2 fitted with a blade 3, and a boss 4. At the same time, the boss 4 consists of a part of the hub 2 with a surface 9 perpendicularly intersecting a drive shaft 6 passed through by the boss 4, and a hollow box. Also, a drive shaft insertion hole 10 of D shape whirl-stop structure is provided on a surface opposed to the surface 9 of the box so as to insert the drive shaft 6 of an electric motor 5. Consequently, although the boss 4 is made of a thin plate as it does not need a sleeve and the like to fix the shaft, the structure can be simplified and the productivity can be improved.
