PROBLEM TO BE SOLVED: To provide a vehicular structure capable of reducing the number of components and simplifying and reducing the weight of a reinforcement structure of a front side member without impairing the collision performance even in a head-on collision. SOLUTION: A front side member reinforcement 8 of recessed section is fitted to a rear half portion 3 of a front side member 1 joined with a bottom side of a floor panel 5 and a front side of a dash panel 6. A hydroform reinforcement 4 which is molded by hydroforming in a rectangular shape so as to be along the longitudinal direction of the rear half portion 3 is fitted to an upper portion of the front side reinforcement 8, and joined with each wall part 3a of the rear half portion 3. A first reinforcing member 9 and a second reinforcing member 10 of recessed section are successively covered on upper sides of the floor panel 5 and the dash panel 6. A plurality of closed sections are formed thereby to realize reinforcement so that a part joined with a front side of the dash panel 6 out of the front side member 1 is not bent to a cabin side.
