To provide a motor unit into which a foreign matter is less likely to intrude from an interval between an inner peripheral edge of a shaft hole which is formed in a case and an output body, and to provide an electric bicycle and a cover member.SOLUTION: A motor unit 3 includes a case 4, a motor 5, an output body 8, a transfer mechanism 31, and a cover member 2. The motor 5 is stored in the case 4. The output body 8 is disposed so as to be rotatable about an axial line while penetrating the case 4 in an axial line direction and passing through a shaft hole 421 that is formed in the case 4. The transfer mechanism 31 is stored in the case 4 and transfers the power from the motor 5 to the output body 8. The cover member 2 covers a gap between an inner peripheral edge of the shaft hole 421 and the output body 8.SELECTED DRAWING: Figure 3

    【課題】ケースに形成された軸孔の内周縁と出力体との間の隙間から異物が侵入しにくいモータユニット、電動自転車及びカバー部材を提供する。【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、伝達機構31と、カバー部材2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、ケース4に形成される軸孔421を通って軸線方向にケース4を貫通して軸線回りに回転可能に配置される。伝達機構31は、ケース4内に収容され、モータ5からの力を出力体8に伝達する。カバー部材2は、軸孔421の内周縁と出力体8との間の隙間を覆う。【選択図】図3
