Abstract
A DC motor has a projection which projects from the bottom surface of the brush-holder plate. The projection extends to outside in the axial direction of the motor. A terminal conductor is inserted into a perforated hole formed in the projection. One end of the terminal conductor is exposed to the outside of the motor from the tip of the projection, while another end of the terminal conductor is connected electrically to the brush. The projection functions as the built in type electrical connector to the motor, which when coupled to a power supply, powers the DC motor.
