A small motor configured to supply current to the rotor winding via a commutator that is in sliding contact with the power supply brushes, and equipped with a positive temperature coefficient thermistor that controls the current to the rotor winding. A pair of brush arms made of a conductive elastic material are formed integrally with a power supply brush inside the cover plate, and a pair of brush arms made of a conductive elastic material are electrically connected to the brush arms and have free ends outside the motor cover plate. a brush arm made of a conductive elastic material and electrically connected to at least one of the brush arms, and at least one of the terminals facing each other; A clamping contact part formed in the shape of a tongue is provided on at least one of the facing parts of the brush arm base and the terminal, and the PTC thermistor can be clamped and held through the clamping contact part or the brush arm base can be clamped and held through the clamping contact part. A small motor equipped with a positive temperature coefficient thermistor, characterized in that it is formed so that it can selectively make direct contact with a terminal.
