To prevent an occurrence of electrocorrosion without involving reduction of functionality or an increase of manufacturing cost.SOLUTION: The vehicular driving device includes a cylindrical rotor shaft that is disposed inside a conductive case body, that is fixed to the inner circumferential surface of a rotor which is rotated with respect to a stator, and that serves as a rotation fulcrum of the rotor, and a metal pipe that passes through the rotor shaft in a non-contact manner. Both ends of the metal pipe in the axial direction are fixed to respective parts of the case body so as to be electrically connected to the case body. Accordingly, the case body and the metal pipe are electrically connected, and a circulation current path passing through the case body and the metal pipe is formed. Therefore, an occurrence of electrocorrosion can be prevented without involving reduction of functionality or an increase of manufacturing cost.SELECTED DRAWING: Figure 2

    【課題】 機能性の低下及び製造コストの高騰を来すことなく電食の発生を防止する。【解決手段】 導電性を有するケース体の内部に配置され、ステーターに対して回転されるローターの内周面に固定されローターの回転支点とされる筒状のローターシャフトと、ローターシャフトに非接触の状態で貫通された金属パイプとを備え、金属パイプは軸方向における両端部がケース体の各一部に固定されケース体と電気的に接続された。これにより、ケース体と金属パイプが電気的に接続されケース体と金属パイプを通る循環電流経路が形成されるため、機能性の低下及び製造コストの高騰を来すことなく電食の発生を防止することができる。【選択図】図2
