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
