PROBLEM TO BE SOLVED: To provide a blower structure inhibiting turbulence of air introduced to a centrifugal fan, applicable to an arrangement with an air passage other than a U-turn shape and easy to manufacture. SOLUTION: A straightening means 18, which comprises three ribs 19 integrally molded with a separation member 13 of a casing 8 and straightens intake air, is provided on an intake side of a blower 2, and an upper end of each rib 19 is supported by a support member 21 formed on an inner wall 20 of an upper main body 12. This allows sending air at a constant air speed to an intake opening 4 of the blower 2 by straightening the intake air with the straightening means 18 when outside air is sent to the blower 2 through an outside air inlet of the casing 8, although the intake opening 4 obliquely intersects the air sending direction and the air is therefore disturbed.
