PROBLEM TO BE SOLVED: To provide a geared motor whose guiding of a motor shaft provides a good compactness along the longitudinal axis of a rotation shaft without sacrificing the dynamic balancing of an electric motor.SOLUTION: A geared motor 1 for a motor vehicle wiper system comprises: a brushless direct current electric motor 2 comprising a rotor 20, a stator 21 presenting electromagnetic excitation coils of the rotor, and a rotation shaft 22 integral with the rotor; and a reduction mechanism 3 connecting the rotation shaft and an output shaft of the geared motor. The rotation guide of the rotation shaft of the rotor is provided solely by two bearings 23, 24 respectively arranged at both longitudinal ends of the rotation shaft.SELECTED DRAWING: Figure 2
