PROBLEM TO BE SOLVED: To provide a body structure expanding the collapsible region of a compartment adjacent to the front section or the rear section of a cabin and improving a collision energy absorbing characteristic. SOLUTION: At a head-on collision of a vehicle, the flexible-rigidity region F of a hood ridge member 13 is collapse-deformed in the axial direction from the input end side then bend-deformed to the inside of the vehicle width direction by the setting of the rigidity difference in the vehicle width direction with a hard-rigidity region R functioning as the center. The longitudinal deformation stroke of the hood ridge member 13 is expanded, thereby the collapsible region of a front compartment FC is expanded to increase a collision energy absorption quantity. An ultra-hard-rigidity region M is folded to the inside of the vehicle width direction on this side of the cabin C and avoids to function as a brace, thus reducing cabin deceleration.
