Abstract
PURPOSE: To manufacture a fan in a simple process by indenting a disc from one side to make several rises on it around a boss.
CONSTITUTION: A centrifugal cooling fan 31 is held on a shaft 3 projecting from a body 2 of a sector-type rotary motor by use of a boss 35 fixed on the deeply drawn center of a steel disc. The disc is indented from one side to make several rises 36 at equal distance with each other which radiate from the center of the boss 35. The rises generate blow at strong as blades of a usual centrifugal fan. No need of cutting off the main plate 37 into several blades brings high mechanical strength.
