<P>PROBLEM TO BE SOLVED: To provide a vehicle frame structure that can raise torsional rigidity of a vehicle body while inhibiting increase in weight. <P>SOLUTION: In the vehicle frame structure having a reinforcement 30 provided inside a frame 10, the frame includes: a first face part 11c and a second face part 12c extending in a direction substantially perpendicular to a rotational-axis M direction of a bending moment occurring when a torsional load acts on a vehicle body; and third face parts positioned between the first and second face parts 11a. 12a and 11b, 12b. The reinforcement includes: third-face connections 31a, 31c of both sides connected to the third face parts of both sides respectively; a first-face connection 31b connected to the first face part side at a corner part 10a; a first-face non-contact part 31f provided away from the first face part; a second-face connection 31d connected to the second face part side at a corner part 10d; and a second-face non-contact part 31g provided away from the second face part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
