To provide a motor unit and an electric vehicle which prevents tooth hammer noise by engagement of output gears.SOLUTION: A motor unit 3 includes a case 4, a motor 5, an output body 8, an input shaft 6, and an output gear 9. The motor 5 is stored in the case 4. The output body 8 is arranged so as to penetrate through the case 4 in a shaft line 600 direction and is rotatable around the shaft line 600. The input shaft 6 is arranged so as to penetrate through the case 4 in a shaft line 600 direction and is rotatable around the shaft line 600. The output gear 9 is mounted on the output body 8, and receives a rotational force of the motor 5 and transmits a rotational force to the output body 8. The output gear 9 has a tooth part 91 formed of the resin.SELECTED DRAWING: Figure 3

    【課題】出力歯車の噛み合いにより歯打ち音が発生しにくいモータユニット及び電動自転車を提供する。【解決手段】モータユニット3は、ケース4と、モータ5と、出力体8と、入力軸6と、出力歯車9と、を備える。モータ5は、ケース4内に収容される。出力体8は、軸線600方向にケース4を貫通して軸線600回りに回転可能に配置される。入力軸6は、軸線600方向にケース4を貫通して軸線600回りに回転可能に配置される。出力歯車9は、出力体8に取り付けられ、モータ5の回転力を受けて出力体8に回転力を伝達する。出力歯車9は、少なくとも歯部91が樹脂により形成されている。【選択図】図3
