To provide a head protection airbag device which can accommodate a folding complete body in a case easily and is capable of restricting even twisting of the folding complete body with accuracy.SOLUTION: The head protection airbag device comprises an air bag 25 and a case 60 made of synthetic resin which accommodates a folding complete body 57 of the folded-up air bag. The air bag includes a seizing hole 44 capable of penetrating a seizing protrusion 65 formed on a case side on an upper edge side. The case makes the seizing protrusion protrude in an outward direction in an outer peripheral surface side of a region covering an upper surface side of the folding complete body. On the upper edge side of the air bag, a portion composing a circumference of the seizing hole includes concavities 40, 41 which are formed by recessing the upper edge of the air bag on a frontward side and a rearward side of the seizing hole and is formed as a tab-like state capable of pulling so as to separate the upper edge side from the folding complete body. In a tab-like portion 43 including the seizing hole, an upper edge 43a is disposed on a line substantially identical to an upper edge 47a of a general part 47 of the air bag adjacent to the tab-like portion.SELECTED DRAWING: Figure 14

    【課題】折り完了体を容易にケースに収納させることができて、かつ、折り完了体の捩じれも的確に規制可能な頭部保護エアバッグ装置を提供すること。【解決手段】エアバッグ25と、折り畳んだエアバッグの折り完了体57を収納する合成樹脂製のケース60と、を備える。エアバッグが、上縁側に、ケース側に形成される係止突起65を貫通可能な係止孔44を、有する。ケースが、係止突起を、折り完了体の上面側を覆っている領域の外周面側において外方に突出させている。エアバッグの上縁側において、係止孔の周縁を構成する部位が、係止孔の前方側と後方側とにエアバッグの上縁を凹ませて形成される凹部40,41を有して、上縁側を折り完了体から離すように引張可能なタブ状とされる。係止孔を有したタブ状部位43が、上縁43aを、タブ状部位と隣接するエアバッグの一般部47の上縁47aと略同一線状に配置させている。【選択図】図14
