ABSTRACT:
In the case of a small-sized motor of the present invention, a printed board to which an electric circuit including an electric element is attached is mounted on a case cover. The printed board has a soldering part to be connected to a member attached to an interior of the case cover for being connected to an electric power source supplied from an outside and a soldering part to be connected to a projection in a notch provided on an opening part side of the metal case to body-earth the electric circuit. In the soldering part for the body-earthing, at the time of assembling the motor, after fitting the case cover to the metal case opening part, a pair of electrodes are brought into contact from an outside of the metal case near the soldering part, to weld the soldering part by a principle of the electric resistance welding. Consequently, it is possible to easily and surely body-earth the earth of the electric circuit to the metal case, and to reduce the number of the motor assembling steps so that the assembling can be performed with a good working property.
