Claims

[Scope of utility model registration request]

In a motor in which a washer-shaped varistor is attached to the rotor side of a commutator attached to the rotor shaft, the brush sliding contact portion of the commutator is formed in a cylindrical shape, and the brush of the metal piece is attached to the rotor side. The varistor has a terminal for connecting the varistor extending from the sliding contact portion, and a terminal for connecting the winding that also projects outward from the sliding contact portion of the brush of the metal piece on the rotor side. A motor in which electrodes are formed on the side surface of the rotor on an inward side away from the outer periphery of the rotor, the electrodes are connected to the varistor connection terminal, and the windings of the rotor are connected to the winding connection terminals. .
