To provide a power control unit mounting structure for a hybrid vehicle, which even when a power control unit (PCU) is arranged in an engine room, prevents breakage of a high-voltage cable due to backward movement of an engine during a frontal collision and hindrance of expected backward movement of the engine.SOLUTION: In a power control unit mounting structure, when viewed from the front of a vehicle, a longitudinally-mounted engine 10 and a toe board cross member 6 are provided with parts thereof overlapping with each other within a projection plane along a front-rear direction so as to have a space behind a power control unit (PCU) 20. An intake manifold 16 and the PCU 20 are arranged within the outline of the longitudinally-mounted engine 10 when viewed from the top of the vehicle, in which the intake manifold 16 is arranged in front of the PCU 20. Both side portions of an intake pipe are extended backward, and the portions of both side surfaces of the PCU 20 are arranged opposite to each other.SELECTED DRAWING: Figure 2

    【課題】 エンジンルーム内にPCUを配置しても、前方衝突時のエンジン後退による高電圧ケーブルの破断や、想定されたエンジン後退の阻害を防止するハイブリット車両のパワーコントロールユニット搭載構造の提供。【解決手段】 パワーコントロールユニット搭載構造は、縦置きエンジン10およびトーボードクロスメンバ6が車両正面視において、PCU20の後方に空間を有するように、前後方向に沿った投影面内に一部分が重なって設けられ、インテークマニホールド16およびPCU20が車両上面視において、縦置きエンジン10の輪郭内に配置され、インテークマニホールド16がPCU20の前方に配置されると共に、インテークパイプの両側一部分が後方に延設してPCU20の両側面と一部分が対向して配置されている。【選択図】図2
