Abstract

A blower with a silencer has the blower including an axial fan including a casing, a motor attached to the casing, and a rotor having a shaft portion attached to the motor and rotated and a blade formed to protrude to an outer side of the shaft portion in a radial direction, and a silencer attached to the casing, in which the silencer includes a resonator that selectively silences a dominant sound generated by the axial fan, the silencer is disposed at a position in which at least a part of the silencer overlaps with the shaft portion, as viewed from a rotation axis direction of the rotor, and in a case in which, in a cross section perpendicular to a rotation axis of the rotor, a circle around the rotation axis, which has a radius of a line connecting the rotation axis and a point of a most distal end of the blade, is defined as a rotation region, an area of the silencer in the cross section perpendicular to the rotation axis is smaller than an area of the rotation region.
