Abstract: An object of the present invention is to provide an electric motor which can prevent electric noise generated from a contact between a brush and a commutator from being radiated and diffused to the outside. An electric motor comprises: an armature shaft 28; a coil 29b attached to the armature shaft 28; a commutator 30 attached to the armature shaft 28, and electrically connected to the coil 29b; a brush through which an electric current is supplied to the commutator 30; a conductive shaft bearing 35 configured to rotatably support the armature shaft 28; a yoke 26 incorporated with the shaft bearing 35, and electrically connected to a ground conductor; a conductive shaft bearing 34 arranged in a direction along a center line of the armature shaft 28, different in position from the shaft bearing 35, and configured to rotatably support the armature shaft 28; and a contact plate 51 electrically connected to the shaft bearing 34, and electrically connected to the ground conductor.

Abstract: A metal gear cover 43, which is provided so as to cover a worm wheel housing 36b, is disposed between a worm wheel 41d and a circuit board 51 and grounded, thereby quickly introducing exogenous noise “ON” such as static electricity to the outside of the sunroof motor 21, even if exogenous noise “ON” enters the sunroof motor 21 and reaches the gear cover 43. Therefore, it is possible to surely prevent exogenous noise “ON” from being reflected to the circuit board 51, and causing the circuit board 51 to malfunction and the like. Furthermore, it is possible to improve reliability of the sunroof motor 21.
