Abstract

PROBLEM TO BE SOLVED: To prevent local deformation of a floor part by linking the lower parts of a plurality of vertical beads in the vicinity of a belt anchor fixed to a floor by lateral beads so as to be greatly away upward from a welding portion of the floor and the back panel. SOLUTION: The lower parts of a plurality of vertical beads 3a in the vicinity of a belt anchor 6 fixed to a floor 4 are linked by lateral beads 3b so as to be greatly away upward from a welding portion 5 of the floor 4 and a back panel 2. Namely, the lateral beads 3b of the lower parts of the vertical beads 3a are made to be greatly away upward with a height of H from an A point with high rigidity which is adjacent to the welding portion 5. As a result, the exfoliation of the welding portion 5 can be prevented because lateral beads 3b become bending points when load is inputted in the belt anchor 6 fixed to the floor 4, deformation amount of a back panel 2 can be increased and load is inputted in the welding portion 5 after load is absorbed by this deformation amount.

Therefore, due to a load input to a belt anchor portion or the like fixed to the floor 4, a point A having high rigidity close to the welding portion 5 is locally deformed as a break point. Therefore, the amount of deformation was small, and a peeling load was generated at the welded portion 5.
