Abstract

PURPOSE: To reduce the weight remarkably and improve toughness of fan by manufacturing blade holding plates with thin layer steel plate, and other blade pieces with aluminum or other proper light metals.
CONSTITUTION: A number of blade pieces 1 called low blades or high blades are made of conventional aluminum and other light metal materials, and the blade holding plates 2 to form and hold them cylindrically is formed in a cylindrical shape with steel plates of proper toughness with the minimum thickness, whereby as the steel plates are employed for the blade holding plates 2 without using such an expensive material as aluminum, so no change can occur in their strength even if the plates thinner than the conventional ones are used because the steel plates are stronger in comparison with aluminum. The blade pieces 1 are also strongly held by notch grooves 3 without generating strain over the whole fan, naturally their weight to be reduced.
