To provide a vehicle body comprising a side frame capable of contributing to increase of an absorption amount of collision energy.SOLUTION: A vehicle body 11 comprises: left and right side frames 12 extending in a vehicle body cross direction, and supporting collision load acting from a front or rear side; and a coupling member 22 which is coupled to open ends of the side frames 12, for restricting displacement of the open ends in a direction where the open ends separate mutually. The side frames 12 are arranged in a manner of sandwiching high strength sections 26a, 26b therebetween in the vehicle body cross direction, and comprise a plurality of low strength sections 27 which has strength lower than that of the high strength sections 26a, 26b in the vehicle body cross direction, and the low strength section 27 has lower strength in the cross direction as the low strength section is closer to the open end.SELECTED DRAWING: Figure 1

    【課題】衝突エネルギーの吸収量の増加に貢献することができるサイドフレームを備える車体を提供する。【解決手段】車体11は、車体前後方向に延びて、前方または後方から作用する衝突荷重を支持する左右のサイドフレーム12と、サイドフレーム12の開放端に結合され、相互に遠ざかる方向に開放端同士の変位を拘束する連結部材22とを備える、サイドフレーム12は、車体前後方向に高強度区間26a、26bを挟んで配置され、車体前後方向に高強度区間26a、26bよりも低強度な複数の低強度区間27を有し、低強度区間27は、開放端に近いものほど前後方向に低い強度を有する。【選択図】図1
