To suppress inhibition of energy absorption of a sub frame and input of a large load to a drive motor at the time of front collision.SOLUTION: A front part structure of an electric vehicle comprises: a body side frame 31 which extends in at least a front-back direction, and is located on both sides in a vehicle width direction; a sub frame 34 which is fastened to a lower part of the body side frame, and has a side member 34a extending in the front-back direction; a power unit room 2 formed inside the sub frame; and a motor housing 5a which is arranged in the power unit room, has a side wall part 12 facing the side member, and accommodates a drive motor 5. The motor housing is arranged so that a lower part of the side wall part is adjacent to the side member. An inclined plane part 14, which contacts the side member bent toward the power unit room at the time of vehicle collision and guides the side member down the motor housing is formed below the side wall part.SELECTED DRAWING: Figure 8

    【課題】前方衝突時のサブフレームのエネルギー吸収の阻害と駆動モータへの大荷重の入力を抑制する。【解決手段】少なくとも前後方向に延び、車幅方向両側に配置されるボデーサイドフレーム31と、ボデーサイドフレームの下部に締結され、前後方向に延びるサイドメンバ34aを有するサブフレーム34と、サブフレームの内側に形成されるパワーユニットルーム2と、パワーユニットルーム内に配設され、サイドメンバに面する側壁部12を有し、駆動モータ5を収容するモータハウジング5aと、を備え、モータハウジングは、側壁部の下部がサイドメンバに隣接するように配設され、側壁部の下方には、車両の衝突時、パワーユニットルームへ向けて折れ曲がったサイドメンバに当接するとともにサイドメンバをモータハウジングの下方へガイドする傾斜面部14が形成されている。【選択図】図8
