To protect a functional component like an IPU when a side collision occurs.SOLUTION: A vehicular body structure 1 includes: a side frame 20 that extends in the back-and-forth direction of a vehicle; a first functional component 10 provided at the internal side of a vehicular widthwise direction of the side frame 20; and a cross member 30 which protrudes downwardly relative to the first functional component 10 from the side frame 20, and which extends in the vehicular widthwise direction. The cross member 30 includes: an extended part 32 that extends outwardly in the vehicular widthwise direction relative to the side frame 20; and a fragile part 33 that is provided inwardly in the vehicular widthwise direction relative to the side frame 20.SELECTED DRAWING: Figure 1
【課題】側面衝突時にIPUなどの機能部品を保護する。【解決手段】車体構造1は、車両の前後方向に延びるサイドフレーム20と、サイドフレーム20の車幅内方側に設けられる第1の機能部品10と、サイドフレーム20から第1の機能部品10の下方に突出し車幅方向に延びるクロスメンバ30と、を備え、クロスメンバ30は、サイドフレーム20よりも車幅外方側に延びる延長部32と、サイドフレーム20よりも車幅内方側に設けられた脆弱部33とを備える。【選択図】図1
