An outer rotor motor is miniaturized, is easier to assemble, and lead ends can be insulated with improved reliability without a drop in motor characteristics. One or a plurality of concave channels provided in the axial direction in a circumferential surface of a housing and one or a plurality of rotation-stopping portions that engage the concave channels are provided in a surface of each coil bobbin that faces the cylinder. Through-holes are provided in the rotation-stopping portions in parallel with the rotor shaft.
