To provide a motor unit which achieves good workability of assembly, and to provide an electric bicycle including the motor unit.SOLUTION: A motor unit 3 includes: a motor 53; an input body 30; a speed reduction mechanism 57; a case 33; a bearing 60; and a bearing support part 3312. The motor 53 has a motor shaft 54. The input body 30 has an input shaft 35 which is rotated by a force transmitted from the exterior and rotates with the input shaft 35. The speed reduction mechanism 57 reduces a speed of rotation of the motor shaft 54 of the motor 53 and transmits the rotation. The case 33 houses the motor 53, the input body 30, and the speed reduction mechanism 57 and has a first split body 331 and a second split body 332. The bearing 60 is located within the case 3. The bearing support part 3312 is attached with the bearing 60 and supports the speed reduction mechanism 57. The bearing support part 3312 is attached to the first split body 331.SELECTED DRAWING: Figure 2

    【課題】組立の作業性が良いモータユニット及びこれを備えた電動自転車を提供する。【解決手段】モータユニット3は、モータ53と、入力体30と、減速機構57と、ケース33と、軸受60と、軸受支持部3312とを有している。モータ53は、モータ軸54を有する。入力体30は、外部から伝達した力によって回転する入力軸35を有し、入力軸35とともに回転する。減速機構57は、モータ53のモータ軸54の回転を減速して伝達する。ケース33は、モータ53と入力体30と減速機構57を収容し、第一分割体331と第二分割体332と、を有する。軸受60は、ケース3の内部に位置する。軸受支持部3312は、軸受60が取り付けられ、減速機構57を支持する。軸受支持部3312は、第一分割体331に取り付けられている。【選択図】図2
