Abstract

A brushless motor includes a plate-shaped armature and a magnet facing either one of a top surface and a bottom surface of the armature. An inner peripheral surface of a base member and an outer peripheral surface of a bearing mechanism contact with each other or face each other in a diametrical direction with an adhesive therebetween in a first fixing part. Further, a rotor yoke and a hub protrusion contact with each other or face each other in a diametrical direction with an adhesive therebetween in a second fixing part. Then, a press-fitting or adhesion is carried out in the other of the first and the second fixing part.
