PROBLEM TO BE SOLVED: To achieve a frame structure which has necessary strength, is simple and excels in productivity, to reduce a number of components and the weight of a vehicle body.SOLUTION: A ladder type chassis is formed of: right and left front side frames 10 linearly extending in the longitudinal direction such that they are inclined at an upward gradient from the front side toward the rear side and the distance of separation between the right and left sides increases according as advancing from the front side toward the rear side; right and left rear side frames 12 which are joined to the rear ends of the front side frames 10 while being offset upward, are inclined at an upward gradient from the front side toward the rear side and linearly extend parallel to each other in the longitudinal direction; front cross members (14, 16, 18) extending in the crosswise direction and connecting the right and left front side frames to each other; and rear cross members (20, 22) extending in the crosswise direction and connecting the right and left rear side frames 12 to each other.SELECTED DRAWING: Figure 1

    【課題】必要な強度を備え、簡素で生産性に優れたフレーム構成を実現し、部品点数の削減と共に車体の軽量化を図ること。【解決手段】前方から後方に向かって上り勾配に傾斜し且つ前方から後方に向かうに従って左右の離間距離が増大するように前後方向に直線状に延在する左右のフロントサイドフレーム10と、フロントサイドフレーム10の後端に上側にオフセットして接合され、前方から後方に向かって上り勾配に傾斜して互いに平行に前後方向に直線状に延在する左右のリヤサイドフレーム12と、左右方向に延在して前記左右のフロントサイドフレームを互いに結合するフロントクロスメンバ(14、16、18)と、左右方向に延在して左右のリヤサイドフレーム12を互いに結合するリヤクロスメンバ(20、22)とでラダー型式のシャーシを構成する。【選択図】図1
