A brushless DC motor. The motor includes a rotating shaft, a bearing rotatably supporting the rotating shaft in radial directions, a support holder made of a plastic material and supporting both the lower end of the rotating shaft and the outer circumferential surface of the bearing, a rotor casing having a rotor magnet therein and rotated along with the rotating shaft, a stator mounted to the outer circumferential surface of the support holder so as to face the rotor magnet and rotating the rotor casing by mutual cooperation with the rotor magnet in response to electricity applied from an external power source, and a plate, to which the support holder is locked using a locking screw. The brushless DC motor has a simple structure and reduces the material cost and assembly cost.
