Abstract
A blower device includes a centrifugal fan rotor arranged to blow-out indrawn air in a direction orthogonal to an indrawing direction, and a motor arranged to rotate the centrifugal fan rotor. The centrithgal fan rotor has a motor cover in proximity to an external peripheral surface of the motor. Openings are provided at a lower part of the motor cover and a motor-cooling air passage is formed such that some of the air blown out from the centrifugal fan rotor is led to a motor-surrounding space formed between the centrifugal fan rotor and the motor and then is discharged through the openings.
