PROBLEM TO BE SOLVED: To provide a toothed motor for an automobile vehicle wiper system capable of providing tightness of a high standard along the longitudinal direction axis of a rotary shaft without sacrificing a dynamic balance of an electric motor.SOLUTION: A toothed motor comprises a brushless DC electric motor 2 of including a rotor 20 of including a magnetic element, a stator 21 having a coil for electromagnetically exciting the rotor and a rotary shaft 22 tightly connected to the rotor and a speed reduction mechanism 3 for connecting the rotary shaft and an output shaft of the toothed motor. According to the present invention, a roller bearing 23 guides the rotary shaft in one of a longitudinal directional end part of the rotary shaft, and a hollow support body 25 supports a magnetic element distributed on the periphery, and is coaxially arranged with the rotary shaft, and rotates together, and the hollow support body is put on the roller bearing, and the hollow support body comprises a series of hole of at least one distributed around the rotary shaft of the hollow support body.SELECTED DRAWING: Figure 2
【課題】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高い水準の緊密さを得ることを可能にする自動車車両ワイパーシステム用の歯車付きモータを提供する。【解決手段】歯車付きモータは、磁気要素を含む回転子20と、回転子を電磁的に励磁するためのコイルを有する固定子21と、回転子にしっかりと接続された回転軸22と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。本発明によれば、ころ軸受23が、回転軸の長手方向端部の一方において、回転軸を案内し、中空支持体25が、周囲に分配された磁気要素を支えるとともに、回転軸と同軸上に配置され、かつ共に回転し、中空支持体は、ころ軸受に被さり、中空支持体は、中空支持体の回転軸の周囲に分配された、少なくとも1つの一連の孔を有する。【選択図】図2
