To provide an electric wheel of such a structure that can restrain wear of a bearing for supporting the output part and a gearwheel of a speed reduction mechanism.SOLUTION: An electric wheel includes a motor part 11 having a motor shaft 31 placed along the medial axis J, a speed reduction mechanism 50 for connection with one side of the motor shaft in the axial direction, an output part 60 located on one side of the motor shaft in the axial direction and to which rotation of the motor shaft is transmitted via the speed reduction mechanism, a first bearing 73 and a second bearing 74 for supporting the output part rotatably around the medial axis, and a wheel 2 attached to the second bearing 74 and the output part. The output part has cylindrical shape surrounding the speed reduction mechanism. The wheel has a first wheel cover 3 spreading radially outward from one side of the output part in the axial direction, a second wheel cover 4 spreading radially outward from the other side of the output part in the axial direction, and a coupling part 5 connecting the first and second wheel covers. The first and second bearings are placed separately from each other in the axial direction, on the radial outside of the output part.SELECTED DRAWING: Figure 2 【課題】出力部を支持する軸受および減速機構の歯車が損耗することを抑制できる構造の電動ホイールを提供する。【解決手段】中心軸Ｊに沿って配置されるモータシャフト３１を有するモータ部１１とモータシャフトの軸方向一方側に接続される減速機構５０とモータ部の軸方向一方側に位置し減速機構を介してモータシャフトの回転が伝達される出力部６０と出力部を中心軸回りに回転可能に支持する第１軸受７３および第２軸受７４と出力部に取り付けられるホイール２とを備える。出力部は、減速機構を囲む筒状である。ホイールは、出力部の軸方向一方側の部分から径方向外側に拡がる第１ホイールカバー３と、出力部の軸方向他方側の部分から径方向外側に拡がる第２ホイールカバー４と、第１ホイールカバーと第２ホイールカバーとを繋ぐ連結部５とを有する。第１軸受および第２軸受は、出力部の径方向内側において、軸方向に互いに離れて配置される。【選択図】図２
