Abstract: When front side members are bent by a front-rear-directional collision of a vehicle, the front side members come in surface, not point, contact with an adjacent member in the vehicle by a contact surface formed at a contact portion.

Further, since the bent front side members stably come in surface, not point, contact with the adjacent member, such as the engine in the vehicle, it is possible to decrease the possibility of unexpected fracturing of the front side members.

Abstract: Disclosed is a vehicle body structure that can improve the absorption performance of a load applied to a vehicle is provided. When a load is applied, the sub-side member retreats as a link member turns. Additionally, the retreat of the sub-side member is suppressed when the link member reaches a termination position of the turning.

Through the above, the sub-side member can move reliably while generating a reaction force to attenuate the load until the member retreats to the target position, and can generate a large reaction force after the member has retreated to the target position.

Abstract: Provided is a vehicle body structure which can improve collision performance. The sub-side member 3 has a deformation cooperative movement portion 7 whose strength is made lower than the deformation suppressing portion 8 on the rear side, at a position ahead of a power unit EG. The sub-side member 3 easily deforms at a position ahead of the power unit EG when the load is applied. The sub-side member 3 can deform in synchronization with the deformation of the front side member 2, in a region ahead of the power unit EG with high strength and a relatively small number of disposition parts. Accordingly, the sub-side member 3 can absorb the load efficiently in cooperative movement with the front side member 2. Additionally, the sub-side member 3 is constructed so as to have a higher strength than the deformation cooperative movement portion 7, on the rear side of the deformation cooperative movement portion 7. Accordingly, the sub-side member 3 sufficiently transmits the load to a rear frame structure structure.
