PROBLEM TO BE SOLVED: To provide a structure for mounting an inverter in a front compartment of a vehicle with excellent space efficiency and excellent impact resistance upon a collision.SOLUTION: An inverter 10 for supplying electric power to a motor for travelling is disposed in a front compartment 3 between a suspension tower 5 and a dash panel 6. The case of the inverter 10 is depressed in a step shape at a position where a surface 14 facing the front side of the vehicle opposes a wheel apron 7. In the steps, the thickness of the case at the corner part in the vehicle back side direction is thicker than the thickness of the case at the other parts. If an obstacle collides from the oblique front side of the vehicle to cause a collision of a suspension 21 to the inverter 10, a stress concentration occurs at the corner parts of the steps. By increasing the thickness of the corner parts, the case of the inverter 10 can withstand the stress concentration.

    【課題】車両のフロントコンパートメントにおいて、空間効率が良く、衝突時の耐衝撃性にも優れたインバータの搭載構造を提供する。【解決手段】走行用のモータに電力を供給するインバータ10は、フロントコンパートメント3においてサスペンションタワー5とダッシュパネル6の間に配置されている。インバータ10のケースは、車両前方を向く面14がホイールエプロン7と対向する位置で段差状に窪んでいる。段差の車両後方側の角部のケース厚みが他の部位のケース厚みよりも大きい。車両斜め前方から障害物が衝突し、サスペンション21がインバータ10に衝突した場合、段差の角部に応力集中が生じる。角部の厚みを大きくすることによって、インバータ10のケースは応力集中に耐え得るようになる。【選択図】図2
