摘要 |
A vehicle body frame structure includes a side frame, a sub-frame, a cabin side support member, an under-floor frame, and a link stay. The sub-frame includes a separate side fastening portion, an adjacent side fastening portion, and a central bending point. In the link stay, a first end portion side is fastened to a lower surface of the cabin side support member together with the adjacent side fastening portion so as to be extractable, and a second end portion side is fastened to the under-floor frame. A nut for fastening the second end portion side of the link stay is held by a lateral wall on a side separating from the floor tunnel portion of the link stay, and the support bolt is fitted into the nut from a lower side of a floor tunnel portion in a vehicle width direction serving as an axis. |
