PROBLEM TO BE SOLVED: To provide a bonnet structure of an automobile 1 that can secure both impact absorption performance for absorbing a collision load from an upper side of a vehicle and supporting rigidity of a bonnet outer panel 41.SOLUTION: A bonnet structure of an automobile 1 has a bonnet 4 constituted of a bonnet outer panel 41 and a bonnet inner panel 42. A bonnet stiffener 46 provided at a tip of the bonnet inner panel 42 is formed integrally with a stiffener main body part 461, a front leg part 462 and a rear leg part 463. The stiffener main body part 461 is provided with: a front work hole 465 and a rear work hole 466, opened along a vehicle longitudinal direction; a width-directional groove bead 467 extending in a vehicle width direction between the front work hole 465 and the rear work hole 466; and a longitudinal-directional groove bead 468 extending in a vehicle longitudinal direction in the vicinities of both ends of the width-directional groove bead 467. The width-directional groove bead 467 is formed in a shape curved toward a rear side of the vehicle, and the longitudinal-directional groove bead 468 is formed in a shape curved toward outside in the vehicle width direction.SELECTED DRAWING: Figure 6

    【課題】車両上方からの衝突荷重を吸収する衝撃吸収性と、ボンネットアウタパネル41の支持剛性とを両立して確保できる自動車1のボンネット構造を提供することを目的とする。【解決手段】ボンネットアウタパネル41とボンネットインナパネル42とでボンネット4を構成した自動車1のボンネット構造であって、ボンネットインナパネル42の先端に備えたボンネットスティフナ46を、スティフナ本体部461と前方脚部462と後方脚部463とで一体形成し、スティフナ本体部461に、車両前後方向に沿って開口した前方作業孔465及び後方作業孔466と、前方作業孔465及び後方作業孔466の間で車幅方向に延びる幅溝ビード467と、幅溝ビード467の両端近傍で車両前後方向に延びる前後溝ビード468とを備え、幅溝ビード467を車両後方に湾曲した形状に形成し、前後溝ビード468を車幅方向外側に湾曲した形状に形成したことを特徴とする。【選択図】図6
