摘要： A vechicle body structure for an automotive vehicle comprising front side frames (21, 21) provided left and right at a front portion of a vehicle body (10) so as to hold a longitudinal center line of the vehicle body therebetween, rear side frames (26, 26) provided left and right at a rear portion of the vehicle body so as to hold the longitudinal center line of the vehicle body therebetween and side sills (23, 23) or floor frames (27, 27) provided left and right so as to hold the longitudinal center line of the vehicle body therebetween and lower than the front side frames and rear side frames when viewed from the side of the vehicle body, the front side frames, rear side frames and side sills or floor frames being connected to each other, and further a floor tunnel having the bottom-open U-shaped cross-sectional structure which extends along the longitudinal center line of the vehicle body between said front side frames and said rear side frames and protrudes upwardly of the side sills (23, 23) or floor frames (27, 27). Auxiliary frames (52, 52) each having a closed cross-sectional structure are provided at an upper portion of the floor tunnel. The auxiliary frames are joined to the front side frames and the rear side frames via extensions (53, 53, 54, 54), each having a closed cross-sectional structure.
