FLOOR STRUCTURE FOR FRAMELESS VEHICLE BODY

摘要

PROBLEM TO BE SOLVED: To greatly prevent a transverse member of the drive system from being broken into pieces by providing a reinforcement flange in which forward and rear end faces in the longitudinal direction of the vehicle of each dissimilar support member are extended in the transverse direction of a vehicle, and orthogonally projecting reinforcement fin extending over the whole length of each reinforcement flange. SOLUTION: A reinforcement flange 13 is provided to give high rigidity to a support leg side 11 of a dissimilar support member 10, a reinforcement fin 14 to be projected forward of or rearward of the dissimilar support member 10 in the longitudinal direction of a vehicle is attached thereto, and orthogonally projected from an inner edge of each reinforcement flange 13 and extended over the whole height. The force to be applied to a floor structure by a collision load in the transverse direction of the vehicle is transmitted between a tunnel side wall 9 and the support leg side 11 of each dissimilar member 10, and the load is reduced in the fitting range of connection screws 7. A transmission bridging piece 6 is surely prevented from being broken into pieces even when such a collision load is received.
