PROBLEM TO BE SOLVED: To provide a tensioner for an electric vehicle capable of downsizing a drive unit, and increasing a tensioner capacity.SOLUTION: A drive unit 10 includes an auxiliary driving wheel 15 engaged with a drive force transmission member, and an electric motor 16 for giving rotational drive force to the auxiliary driving wheel 15. A tensioner 18 includes an arm 26 rockably provided on the drive unit 10, a tension applying wheel 27 provided on the arm 26, and energizing means 28. The tension applying wheel 27 is engaged with the drive force transmission member from the opposite side of the auxiliary driving wheel 15. The energizing means 28 energizes the arm 26 in a direction in which the tension of the drive force transmission member increases, and a rocking axis 25 of the arm 26 is the same axis as a rotation axis 37 of the auxiliary driving wheel 15.SELECTED DRAWING: Figure 4

    【課題】駆動ユニットを小型化でき、テンショナーキャパシティーを増大させることが可能な電動車両のテンショナーを提供する。【解決手段】駆動ユニット10は、駆動力伝達部材に歯合する補助駆動用輪体15と、補助駆動用輪体15に回転駆動力を付与する電動機16とを有し、テンショナー18は、駆動ユニット10に揺動自在に設けられたアーム26と、アーム26に設けられた張力付与輪体27と、付勢手段28とを有し、張力付与輪体27は補助駆動用輪体15と反対側から駆動力伝達部材に歯合し、付勢手段28は駆動力伝達部材の張力が増える方向へアーム26を付勢し、アーム26の揺動軸心25が補助駆動用輪体15の回転軸心37と同軸である。【選択図】図4
