Abstract: To suppress deformation of a vehicle cabin by efficiently absorbing an impact load obliquely from a vehicle front side, a vehicle-body front structure includes an upper-side cross member, a lower-side cross member, upper-side impact absorption members that support respective ones of both vehicle-width-direction sides of the upper-side cross member, and lower-side impact absorption members that support respective ones of both vehicle-width-direction sides of the lower-side cross member. The upper-side impact absorption members and the lower-side impact absorption members are each positioned farther on a vehicle-width-direction outer side at a position farther on a vehicle front side.

Abstract: There are provided an outer panel, an inner panel, a second reinforcement provided in the main closed-cross section and cooperates with the outer panel to form a sub closed-cross section extending longitudinally, a bead portion formed at a portion of the inner panel which is located at a position corresponding to the second reinforcement, and configured to be a starting point causing bending of a front side frame toward the second reinforcement when a collision load is applied in a vehicle collision, and a second attaching member provided at a position located on a front-end side of the front side frame relatively to the second reinforcement and configured to make the second reinforcement crushable in a bending direction in the vehicle collision. The second attaching member comprises a knot-shaped member provided inside the main closed-cross section.

Abstract: To suppress damage on a bonnet at light collision, a vehicle-body structure includes rear-portion crush cans that perform compressive deformation when a first predetermined load is applied, and front-portion crush cans that perform compressive deformation when a second predetermined load smaller than the first predetermined load is applied. A front portion of a bonnet is positioned on a vehicle rear side of front portions of the rear-portion crush cans.
