To inhibit increase of a weight and inhibit damage of a harness 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.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 with the electric unit 30 and the motor 21 respectively attached to upper and lower parts of a cross member 8. The electric unit 20 includes: an inverter 40; a junction box 50 which is stacked on the inverter 40 and connected to a battery and the motor; and a bus bar 80 inserted into the inner side of the inverter 40 and the junction box 50 in a vertical direction. The bus bar 80 includes: an input bas bar 81 connecting an inverter input part 47 with a tip part of a battery harness 70; and an output bus bar 82 connecting an inverter output part 48 with a tip part of a motor harness 75.SELECTED DRAWING: Figure 5

    【課題】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、重量の増大を抑制しつつ、前突時におけ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、モータルーム1にクロスメンバ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20は、インバータ40とこの上に積層されておりバッテリ及びモータに接続されたジャンクションボックス50と、インバータ40とジャンクションボックス50とをこれら内側の上下間にわたって挿通されたバスバー80とを含んでおり、バスバー80は、インバータ入力部47とバッテリハーネス70の先端部とを接続する入力用バスバー81と、インバータ出力部48とモータハーネス75の先端部とを接続する出力用バスバー82とを含んでいる。【選択図】図5
