Abstract
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 air blower is a centrifugal air blower which generates a radial airflow perpendicular to the central axis. The holder includes a base supporting the motor, attachments on a radial directional-outer side of the impeller, arms connecting the base and each of the attachments, and a wall surface on a side of the impeller, between the base and each attachment, and opposing a radial-directional inner side. An axial lower end of the impeller is located below an axial upper end of the wall surface.
