To provide a motor unit which is improved in lubrication performance and accordingly can be downsized, and a motor unit body and an electric bicycle.SOLUTION: A motor unit 2 is used for an electric bicycle which can run by adding drive auxiliary output generated by a motor to man-power driving force. The motor unit 2 comprises a housing 21, a motor, an output body 33, a gear 44, and oil 54. The motor is mounted on the housing 21. The output body 33 outputs drive auxiliary output from the motor. The gear 44 transmits the drive auxiliary output output from the motor 36 to the output body 33, and is housed in the housing 21. The oil 54 is stored in the housing 21 and performs oil lubrication on the gear 44. In the motor unit 2, at least part of the gear 44 is soaked in the oil 54 while the rotary shaft of the output body 33 is along a horizontal surface.SELECTED DRAWING: Figure 4

    【課題】潤滑性能を向上させ、小型化が可能なモータユニット、モータユニット本体及び電動自転車を提供する。【解決手段】モータユニット2は、人力駆動力に、モータにより発生する駆動補助出力を加えて走行可能である電動自転車に用いられる。モータユニット2は、筐体21と、モータと、出力体33と、歯車44と、油54と、を備える。モータは、筐体21に取り付けられる。出力体33は、モータからの駆動補助出力を出力する。歯車44は、モータ36から出力された駆動補助出力を出力体33に伝達し、筐体21に収まる。油54は、筐体21に貯められ、歯車44に対し油潤滑を行う。モータユニット2は、出力体33の回転軸が水平面に沿った状態で、歯車44の少なくとも一部が油54に浸かる。【選択図】図4
