囲第１項に記載の電動ファン。(1) A fan that is attached to the shaft of the motor and blows air sucked in from the axial direction of the shaft in the radial direction of the shaft, and this fan is coupled to the shaft or to the bowl-shaped resin coreless armature that is connected to the shaft. The coreless armature is rotated by a field part and a brush provided inside the coreless armature, and has a commutator on a side surface of the coreless armature on the fan side that contacts the brush. An electric fan according to the invention, wherein a hole passing through the coreless armature is provided on a back surface of a commutator of the coreless armature. (21) The electric fan according to claim 1, wherein the shaft projects from the inside of the coreless armature toward the fan and forms a cooling section that receives wind from the fan.
