摘要： Four tapered portions are formed on an end portion of an inner wall surface of an air channel at four locations corresponding to four corners of the profile of a surface of a housing where a suction port is formed. The four tapered portions are each inclined outwardly in a radial direction of a rotary shaft from a discharge port side toward the suction port side and extending in a rotational direction of an impeller. The tapered portions each include a main portion which is shaped such that an angle formed between the main portion and an axis of the rotary shaft gradually becomes smaller from one end of the main portion located rearward as viewed in the rotational direction of the impeller toward the other end of the main portion located forward as viewed in the rotational direction of the impeller.

摘要： An axial flow fan provided herein allows for a wide range of selection for placement of the fan and wiring of the lead wires. The axial flow fan includes a first lead wire engaging portion 17 configured to be engaged with a plurality of lead wires 15 such that the lead wires are pulled out therefrom into an outer space OS defined between a first flange 21 and a second flange 23 of a fan housing 3, a second lead wire engaging portion 19 configured to be engaged with the plurality of lead wires 15 such that the lead wires, which have been engaged with the first lead wire engaging portion 17 and pulled out therefrom into the outer space OS, are then pulled out toward the other side in the axial direction where the second flange 23 is positioned, and a third lead wire engaging portion 27 configured to be engaged with the plurality of lead wires 15 such that the lead wires, which have been engaged with the first lead wire engaging portion 17 and pulled out therefrom into the outer space OS, are then pulled out in the axial direction toward one side where the first flange 21 is positioned. The third lead wire engaging portion 27 is formed in the first flange 21 at a given distance from the first lead wire engaging portion 17.
