Abstract

A blower includes a moving blade rotatable about a central axis, a motor to rotate the moving blade, a housing, and a substrate. The housing includes a holding portion below the moving blade to hold the motor, and a peripheral wall portion having a cylindrical shape extending upward from a radially outer end portion of the holding portion. The peripheral wall portion includes a peripheral wall recess recessed downward from an upper end of the peripheral wall portion and connecting a space radially inside and a space radially outside of the peripheral wall portion. The peripheral wall recess includes a first peripheral surface that opposes one circumferential direction opposite to a rotation direction of the moving blade, the first peripheral surface extending from an upper end of the peripheral wall recess toward a lower side of the peripheral wall portion.
