Zusammenfassung:	An air blower includes an impeller rotatable about a central axis extending vertically, a motor to rotate the impeller, and a holder to hold the motor. The holder includes a base on which the motor is provided, attachments on a radial directional-outer side of the impeller, arms connecting the base and the attachments, and a wall surface on a side where the impeller is disposed, between the base and each attachment, and facing a radial-directional inner side. The wall surface includes a first surface extending outwardly in the radial direction and directed towards the front in the rotational direction of the impeller.
