摘要： An axial flow fan includes: an impeller, a hub of which is attached to a rotation shaft of a rotation driving device; and a venturi casing that surrounds an outer circumference in a radial direction of the impeller and includes a suction port and a discharge port facing each other in an axial direction of the rotation shaft. A positive pressure surface of a plurality of blades integrally attached to the hub includes a plurality of step portions that is curved so as to comply with a curved shape of a front edge portion in a rotation direction of the blades.

摘要： Four tapered portions (65) are formed on an end portion of an inner wall surface of an air channel (48) at four locations corresponding to four corners of the profile of a surface (52) of a housing (5) where a suction port (51) is formed. The four tapered portions (65) are each inclined outwardly in a radial direction of a rotary shaft (9) from a discharge port (53) side toward the suction port side and extending in a rotational direction of an impeller (3). The tapered portions (65) each include a main portion (65A) which is shaped such that an angle (θ1-θ4) formed between the main portion (65A) and an axis (A) of the rotary shaft (9) gradually becomes smaller from one end (65g) of the main portion (65A) located rearward as viewed in the rotational direction of the impeller (3) toward the other end (65e) of the main portion (65A) located forward as viewed in the rotational direction of the impeller (3).
