Abstract
A blower includes an impeller that is rotatable about a central axis extending in a vertical direction, a motor that rotates the impeller, and a base portion on which the motor is mounted. The impeller includes a cup portion that covers the motor, and blades extending radially outward from the cup portion and arranged in a circumferential direction. A gap is provided between the cup portion and the base portion such that the gap becomes narrower in an outward direction with increasing distance from an interior of the cup portion.
