ABSTRACT:
The present invention provides an axial flow fan capable of increasing an air volume and a static pressure more than conventional axial flow fans, and also capable of reducing generation of noise. A guide wall portion33is provided to form a guide groove31between the guide wall portion33and one stationary blade11. The one stationary blade11is disposed in the vicinity of a lead wire engaging portion25provided at a housing3. The guide groove31receives a plurality of lead wires10and guides the lead wires10to the lead wire engaging portion25. When the guide wall portion33is provided and the lead wires10are received in the guide groove31, presence of the lead wires10may have less adverse effect on the air volume and the static pressure, and may generate less noise.
