Summary:PURPOSE:To make it possible to strengthen the blade of a multiblade fan in strength by assembling the blade while combining an aluminum material and a steel plate material to permit them to reinforce with each other. CONSTITUTION:All blades and supporting plates for assembling the blade are constructed by aluminium plates. When a somewhat thicker light metal plate such as aluminium having the thickness (t') is used for the blade 1 in view of its strength, etc., irrespective of a low blade or a high blade, a thin steel plate having the thickness of (t) is, against said plate, used for both side supporting plates 2 or an intermediate plate 2 for supporting the blade. On the other hand, when a light metal plate having the thickness (t) is used for a blade, one having the thickness t' is used for the supporting plate 2 to reinforce the strength of a blade.
