To provide a vehicle body frame that can reduce a maximum load required to bend a frame member at the time of a collision and can effectively absorb collision energy due to the collision.SOLUTION: A vehicle body frame includes frame members 5A11,5A12 arranged in a direction in which a load is applied at the time of a collision and deformable to be bent at a predetermined bending position by the collision and a bend restriction member 5A2 arranged along the frame members and connected to one of the frame members in an area thereof on the border with the predetermined bending position. The bend restriction member is separated from the other of the frame members in the other area until one of the frame members is bent with a predetermined amount, and in the meantime the bent restriction is brought into interference with the other of the frame members when one of the frame members is bent with the predetermined amount.SELECTED DRAWING: Figure 5

    【課題】衝突による骨格部材が折れ曲がるのに要する最大荷重を抑制しつつ、衝突による衝突エネルギーを効率的に吸収することができる車体フレームを提供する。【解決手段】車体フレームは、衝突時に荷重が加わる方向に沿って配置され、衝突によって所定の折れ曲がり位置にて折れ曲がり変形可能な骨格部材5A11,5A12と、骨格部材に沿って配置され、所定の折れ曲がり位置を境に骨格部材の一方の領域において骨格部材に接合された折れ曲がり規制部材5A2と、を備え、折れ曲がり規制部材は、骨格部材が所定量折れ曲がるまで骨格部材の他方の領域にて骨格部材に離隔する一方、骨格部材が所定量折れ曲がると骨格部材に干渉する。【選択図】図5
