PROBLEM TO BE SOLVED: To provide a vehicular frame structure capable of transmitting a load inputted into a frame body to a reinforcement body, and also capable of increasing an energy absorbing quantity while suppressing weight increase.SOLUTION: In a vehicle body frame 1 in which a reinforcement body 20 is provided inside a frame body 10, the reinforcement body 20 has a plurality of closed cross sectional parts and connection parts for connecting the closed cross sectional parts adjacent to each other. The closed cross sectional parts include a pair of first surface parts facing each other and a pair of second surface parts facing each other. The second surface parts are formed in a substantially rectangle cross sectional shape in which the second surface parts are longer than the first surface parts, and are arranged in a direction in which the second surface parts are approximately orthogonal to a neutral axis for bending. A first knot-form member 30 and a second knot-form member 40 bonded to the frame body 10 are respectively bonded to one side and the other side of the frame body 10 in the longitudinal direction in the reinforcement body 20.

    【課題】フレーム本体に入力された荷重を補強体に伝達することができ、重量の増加を抑制しつつエネルギ吸収量を高めることができる車両用フレーム構造を提供する。【解決手段】フレーム本体10の内部に補強体20が配設された車体フレーム1において、補強体20は、複数の閉断面部と隣り合う閉断面部を連結する連結部とを有し、閉断面部が、互いに対向する一対の第1面部と一対の第2面部とを備え、第2面部が第1面部より長い断面略長方形状に形成されると共に第2面部が曲げの中立軸と略直交する方向に配置され、補強体20におけるフレーム本体10の長手方向一方側及び他方側に、フレーム本体10に接合された第1節状部材30及び第2節状部材40がそれぞれ接合されている。【選択図】図2
