<P>PROBLEM TO BE SOLVED: To provide a vehicle frame structure which can efficiently enhance bending rigidity while suppressing increase in weight. <P>SOLUTION: In the vehicle frame structure 1, a reinforcement body 20 is built in a frame body 10. The frame body 10 includes: a first face part 11a to which force in a compression direction is applied and a second face part 12a to which force in a tensile direction is applied, when a bending load is applied from outside; and third face parts 11b positioned on both sides and forming corner parts 10a, 10b with the first face part 11a and the second face part 12a, respectively. The reinforcement body 20 includes: first abutment parts 20a positioned on both sides and made to abut on corner part inner faces corresponding to the corner parts 10a formed between the first face part 11a and the third face parts 11b on both sides, respectively; a second abutment part 20b made to abut on and correspond to the central side of the second face part 12a; and non-abutment parts 20c positioned on both sides and separated from the third face parts 11b not to abut on the third face parts 11b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
