摘 要：
PROBLEM TO BE SOLVED: To provide a miniaturized centrifugal fan realizing simultaneously high wind sending
performance and low noise by keeping largely a channel inlet area between blades while reducing the inside
diameters of the blades.;SOLUTION: This centrifugal fan comprises an electric motor of an external rotation type radial gap system or an axial gap system, an impeller having a vessel type projecting part for retaining a rotor in its inside and two or more blades arranged around the projecting part, a rotary shaft for rotatably supporting the impeller to a stator, and a scroll type casing with the impeller stored, the stator attached, an air suction port provided above the impeller, and an air supply opening provided to a side wall. Regarding all two or more blades or
partial blades among two or more blades, one portion of the blades is brought into contact with the projecting part, and the outer end of the rotor is positioned farther outward in a radial direction than the
