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

    【課題】モータ軸の案内は、電気モータの動的平衡を犠牲にすることなく、回転軸の長手方向軸に沿った良好な緊密さを得る歯車付きモータを提供する。【解決手段】自動車両ワイパーシステム用歯車付きモータ1は、回転子20、回転子の電磁石の励磁用のコイルを有する固定子21、および回転子と一体の回転軸22を含むブラシレス直流電気モータ2と、回転軸と歯車付きモータの出力軸とを連結する減速機構3とを備えている。回転子の回転軸の回転案内は、回転軸の2つの長手方向端部にそれぞれ設置された2つのころ軸受23、24のみによって行われる。【選択図】図2
