PROBLEM TO BE SOLVED: To provide a pedestrian protection airbag-mounted hood device which can reduce the chattering vibration of a hood rear part which is mounted with a pedestrian protection airbag at the traveling of a vehicle.SOLUTION: In a pedestrian protection airbag-mounted hood device 10, a pedestrian protection airbag 60 is mounted to a lower side of a hood rear part 22. A stopper 30 which can regulate a closed end side at the opening/closing of a hood is arranged at a lower part of a hinge 28. The stopper 30 has hood-side stopper rubber 32 and vehicle-side stopper rubber 34. Either of the stopper rubbers 32, 34 is formed into a protrusive shape in a hood fore-and-aft direction L, and the other is formed into a recessive shape. The protrusive shape is rushed into the recessive shape at the closing of the hood 20. As a result, relative vibration displacement between the protrusive shape and the recessive shape in a hood width direction W is reduced, and the chattering vibration of a hood rear part 22 is reduced and alleviated. At the opening of the hood 20, the protrusive shape is separated from the recessive shape in the hood fore-and-aft direction L, and an opening/closing function of the hood 20 is not impaired.SELECTED DRAWING: Figure 2
【課題】歩行者保護用エアバッグを搭載したフード後部の車両走行時におけるびびり振動を低減できる歩行者保護用エアバッグ搭載型フード装置の提供。【解決手段】歩行者保護用エアバッグ搭載型フード装置10では、フード後部22の下側に歩行者保護用エアバッグ60が搭載されている。ヒンジ28の下方にフード開閉の閉端側を規制可能なストッパ30が設けられる。ストッパ30は、フード側ストッパゴム32と車両側ストップゴム34を有する。ストッパゴム32、34の一方はフード前後方向Lに凸型形状に他方は凹型形状に形成される。フード20閉時には凸型形状が凹型形状に突入される。その結果、フード幅方向Wの凸型形状と凹型形状との相対振動変位が低減され、フード後部22のびびり振動が低減され、かつ減衰される。フード20開時には凸型形状がフード前後方向Lに凹型形状から離反され、フード20開閉機能は損なわれない。【選択図】 図2
