PROBLEM TO BE SOLVED: To inhibit a part of a case from hampering expansion of an airbag.SOLUTION: A pedestrian protection airbag device 10 includes: an inflator which is operated to generate a gas; an airbag which is supplied with the gas generated by the inflator to expand; and an upper case 28 which is provided at the lower end side of front windshield glass and forms a part of a case in which the airbag is housed. Tear lines 32 which become rupture starting points when the airbag expands are formed at a boundary between an upper wall part 28A and a rear wall part 28C of the upper case 28, a boundary between the upper wall part 28A and a right side wall part 28D, a boundary between the upper wall part 28A and a left side wall part 28E, a boundary between the rear wall part 28C and the right side wall part 28D, and a boundary between the rear wall part 28C and the left side wall part 28E.SELECTED DRAWING: Figure 4

    【課題】ケースの一部がエアバッグの展開の妨げとなることを抑制する。【解決手段】歩行者保護エアバッグ装置10は、作動されることでガスを発生させるインフレータと、インフレータが発生したガスが供給されることで膨張するエアバッグと、フロントウィンドシールドガラスの下端側に設けられ、かつエアバッグが内部に収容されるケースの一部を構成する上ケース28を備えている。上ケース28の上壁部28Aと後壁部28Cとの境目、上壁部28Aと右側側壁部28Dとの境目、上壁部28Aと左側側壁部28Eとの境目、後壁部28Cと右側側壁部28Dとの境目、及び後壁部28Cと左側側壁部28Eとの境目には、エアバッグが膨張した際に破断起点となるティアライン32が形成されている。【選択図】図4
