Abstract

PURPOSE:To prevent a filler pipe from its deformation, when collision or the like takes place, by additionally providing a protector, positioned respectively in the rear and the bottom of the filler pipe and having respectively reinforced rear and bottom wall parts, in a side frame in its bottom surface. CONSTITUTION:A protector 10 forms its rear wall part 10a overlapping a rear plate part 14 of a protector main unit with a rear plate part 27 of a reinforcement 12. While the protector 10forms its bottom wall part 10b by a bottom plate part 13 of a protector assembly 11. Further the protector 10 fixes its front part to the bottom surface of a side frame 1 through a mounting plate part 21 of the assembly 11 and a protruding part 26a of the reinforcement 12. By this structure thus obtained, when the side frame 1 moves its rear part to the front by collision, the bottom wall part 10b generates almost no deformation while deforming an upper wall part 10c and a front wall part 10d into an arched shape. Accordingly, a filler pipe 2 enables its space to be ensured.
