摘要： A fan frame accommodates a fan for blowing air or cooling and has a hole into which a tapping screw is fixed. The hole has a first hole portion opened in an attachment surface onto which a supporting member fixed by the tapping screw is attached and a second hole portion extending from the first hole portion and having a predetermined inner diameter. The first hole portion of the hole is formed to have a diameter larger than that of the second hole portion.

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).
