PROBLEM TO BE SOLVED: To suppress generation of hitting point crack by preventing concentration of stress of a joining part for joining a center floor to a rear floor in a bonding structure of a floor end for a vehicle. SOLUTION: A center floor 14 is spot-welded 32 with a rear side member 10 and a rear wheel house inner 12 at three-sheet pile at a vehicle rear side at an outer end side in a vehicle width direction of the floor, a rear floor 16 is spot-welded 36 with the rear side member 10 and the rear wheel house inner 12 at three-sheet pile at a vehicle front side, and the center floor 14 and the rear floor 16 are not directly joined. Thereby, even if the center floor 14 and the rear floor 16 perform independent motion respectively, stress is not concentrated to the outer end part in the vehicle width direction of the center floor 14 and the rear floor 16, and generating of hitting point crack is suppressed.
