Abstract

PURPOSE: To make variable the performance of air blower by providing a long hole for holding fitting screw to casing to which driving motor and casing are attached and by attaching casing to it by moving to any direction.
CONSTITUTION: The impeller 4 is directly connected to the driving motor 1 and the casing 3 is attached to the motor 1 with the fitting screw 2. The long hole 3a for holding the fitting screw 2 is formed in the casing longitudinally on each parallel line, whereby the aperture δ between the casing 3 and the impeller 4 can be made larger or smaller by moving it to the moving direction of casing when the casing 3 is attached and therefore the outside dimension Cθ of the casing 3 is determined. Thus, the enlarging angle α of casing can be made smaller or larger and the performance of air blower can be freely varied.
