PROBLEM TO BE SOLVED: To provide a collision load alleviation structure capable of securely reducing a collision load transmitted to a battery.SOLUTION: A collision load alleviation structure comprises: a pair of vehicle body frames 1 arranged spaced apart in a vehicle width direction, extending longitudinally and formed so that the closer to a rear end part and farther from a front end part thereof, the wider a distance between the vehicle body frames of the pair gradually becomes; and a battery frame 12 arranged inside the pair of the vehicle body frames 1 and supporting a battery 3. The battery frame 12 comprises a pair of side part frames 14a which is arranged spaced apart in the vehicle width direction, extending longitudinally and at least a front end part of which is formed so that the closer to a rear end part and farther from a front end part thereof, the wider a distance between the pair gradually becomes along the pair of vehicle body frames 1. In the pair of side part frames 14a, an outer side surface 19b facing an inner side surface 18a of the pair of the vehicle body frames 1 is inclined from an upper edge part toward a lower edge part.SELECTED DRAWING: Figure 3
【課題】バッテリへ伝達される衝突荷重を確実に減少させる衝突荷重緩和構造体を提供する。【解決手段】車幅方向に間隔を空けて配置され、前後方向に延びると共に前端部側から後端部側に向かって徐々に互いの間隔が広くなるように形成された一対の車体フレーム1と、一対の車体フレーム1の内側に配置されてバッテリ3を支持するバッテリフレーム12とを備え、バッテリフレーム12は、車幅方向に間隔を空けて配置されて前後方向に延びると共に少なくとも前端部側が一対の車体フレーム1に沿って前端部側から後端部側に向かって徐々に互いの間隔が広くなるように配置された一対の側部フレーム14aを有し、一対の側部フレーム14aは、一対の車体フレーム1の内側面18aに対向する外側面19bが上縁部から下縁部に向かって傾斜する。【選択図】 図3
