To provide a reinforcement structure for a vehicle body panel of a motor vehicle in which a space between a vehicle body panel forming a vehicle body of a motor vehicle and a reinforcement panel which reinforces the vehicle body panel is sealed by a sound insulation member for prevention of sound leakage.SOLUTION: A longitudinal bead wall part 42a and belt-like bead wall parts 44a, 44d, 44e, 44f open from an outer peripheral edge part of a reinforcement panel 40 to a vehicle cabin at each of extension end parts (openings). A sound insulation member 50 for prevention of sound leakage seals the outer peripheral edge part of the reinforcement panel 40 with each of the extension end parts (the openings) of the longitudinal bead wall part 42a and the belt-like bead wall parts 44a, 44d, 44e, 44f in an air-tight manner.SELECTED DRAWING: Figure 6
【課題】自動車の車体を構成する車体パネルと当該車体パネルを補強する補強パネルとの間を音漏れ防止用遮音部材により封止するようにした自動車の車体パネル用補強構造を提供する。【解決手段】長手状ビード壁部42a、帯状ビード壁部44a、44d、44e、44fは、その各延出端部(開口部)にて、補強パネル40の外周縁部から車室内に開口している。音漏れ防止用遮音部材50は、補強パネル40の外周縁部を、長手状ビード壁部42a、帯状ビード壁部44a、44d、44e、44fの各延出端部(各開口部)と共に気密的に封止する。【選択図】図6
