The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. Reinforcement for reinforcing a vehicle frame structure (10) including a pair of lateral side frame members (11) extending in a lateral direction of the vehicle, and at least one cross frame member (12) connecting the side frame members (11) at a predetermined position of the side frame member (11), each of the side frame members (11) having a kick-up frame (13) inwardly bent at the end thereof, characterized in that the reinforcement (30) is installed at the interconnection of the side frame member (11) with the kick-up frame (13) of the side frame member (11).
2. Reinforcement according to claim 1, wherein said reinforcement (30) has a flat top section (20) in parallel to a top section of the side frame member (11) and a slope section (21) which is inclined downwardly having a hollow, triangular shape.
3. Reinforcement according to claim 2, wherein said top section (20) and said slope section (21) include flanges (22, 23) integrally curved at the end thereof so that top section (20) and the slope section (21) may be fixed and welded to be in contact with upper and lower portions of the side frame member (11).
