Abstract
A thin motor-driven centrifugal blowing fan apparatus draws in air in a rotation-axis direction and discharges the air in a radial direction. In this fan apparatus, blades are fitted on a peripheral face of a rotor, and each section of the blades in the vicinity of the peripheral face is implanted at an acute angle to the rotation direction so as to form an axial blade section. A section extending from the axial blade section is arranged perpendicular to the rotation direction so as to form a centrifugal blade section.
