To prevent deformation in a vehicle width direction at the time of a collision.SOLUTION: A vehicle front part structure includes: rockers 14 extending in a vehicle front-back direction at vehicle side portions; under reinforcements 16 extending parallel to the rockers 14 at an inner side in a vehicle width direction of the rockers 14; a center tunnel 18 extending parallel to the under reinforcements 16 at an inner side in the vehicle width direction of the under reinforcements 16; brace reinforcements 22 each connecting side walls of the under reinforcement 16 and the rocker 14; and front part cross members 40 each connecting side walls of the under reinforcement 16 and the center tunnel 18. The front part cross member 40 includes a first connection portion connecting to the under reinforcement 16 and a second connection portion connecting to the center tunnel 18. The first connection portion is arranged at a position in an extension direction in which the brace reinforcement 22 extends toward the under reinforcement 16.SELECTED DRAWING: Figure 1

    【課題】衝突時における車幅方向の変形を抑制する。【解決手段】車両側部において車両前後方向に伸びるロッカ14と、ロッカ14の車幅方向内側においてロッカ14に対し平行に伸びるアンダリンフォース16と、アンダリンフォース16の車幅方向内側においてアンダリンフォース16に対し平行に伸びるセンタトンネル18と、ロッカ14とアンダリンフォース16の側壁とを接続する筋交リンフォース22と、アンダリンフォース16の側壁とセンタトンネル18の側壁とを接続する前部クロスメンバ40と、を含む。前部クロスメンバ40は、アンダリンフォース16と接続する第1接続部と、センタトンネル18と接続する第2接続部と、を含み、第1接続部は、筋交リンフォース22がアンダリンフォース16に向かって伸びる方向の延長上に配置される。【選択図】図1
