To inhibit a harness from being damaged by contact with a vehicle body component located at the rear side during a frontal collision in an electric vehicle in which the harness is connected to a rear surface of an electric unit stacked on a motor in a motor room.SOLUTION: A front part unit mounting structure of an electric vehicle includes an electric unit 30 and a motor 21, which is supplied with electric power from the electric unit 30, in a motor room 1 formed at a vehicle front part with the electric unit 30 and the motor 21 attached to upper and lower parts of a cross member 8 extending in a vehicle width direction. The electric unit 30 includes a junction box 50 with which battery harnesses 70 and motor harnesses 75 for supplying electric power for driving the motor 21 from a battery 11 are connected. The junction box 50 has: a harness connection part 57 with which the harnesses 70, 75 are connected; and a protruding part 69 protruding to the rear side relative to the harness connection part 57.SELECTED DRAWING: Figure 5

    【課題】モータルームにおいて、モータの上方に積層された電気ユニットの後面にハーネスが接続された電動車両において、前突時における、後方に位置する車体部品との接触によるハーネスの損傷を抑制する。【解決手段】電動車両の前部ユニット搭載構造は、車両前部に形成されたモータルーム1に、車幅方向に延びるクロスメンバ8の上下に取り付けられた、電気ユニット30と、これから給電されるモータ21とを備え、電気ユニット30はバッテリ11からモータ21を駆動するための電力を供給するためのバッテリハーネス70及びモータハーネス75が接続されるジャンクションボックス50を含んでおり、ジャンクションボックス50は、ハーネス70,75が接続されるハーネス接続部57と、ハーネス接続部57よりも後方に突出する突出部69とを有している。【選択図】図5
