To provide a folding completion body of an airbag that can perform upward projection near a center of a receiving sire wall portion at the time of initial flow of expansion pass, and elimination of a folding part of radial folding.SOLUTION: An outer peripheral edge while a vehicle body side wall portion 32 and a receiving side wall portion 35 on an outer peripheral wall 31 of an airbag 30 are developed, is radially folded so as to be collected to an inflow opening 33 side, and a storage recessed portion 52 for storing an upper part 18b of an inflator 18 for supplying expansion gas is provided on a bottom surface 51. A straight line-shaped supply path 58 supplying the expansion gas G from the inflator to a center inside surface 36 of the receiving side wall portion is formed so as to linearly extend from the storage recessed portion. A radially folded part 56 is arranged so as to surround the periphery of an intermediate part 58b between a base portion 58a and a tip end portion 58c of the straight line-shaped supply path, around the storage recessed portion.SELECTED DRAWING: Figure 4

    【課題】膨張用ガスの流入初期時の受止側壁部の中央付近の上方への突出と、ラジアル折りの折畳部位の折りの解消と、を迅速に行えるエアバッグの折畳完了体を提供すること。【解決手段】エアバッグ30の外周壁31における車体側壁部32と受止側壁部35とを展開させた状態の外周縁を、流入用開口33側に集めるラジアル折りして、折り畳み、底面51に、膨張用ガス供給用のインフレーター18の上部18bを収納する収納凹部52を備える。インフレーターからの膨張用ガスGを受止側壁部の中央内側面36に供給する直線状供給路58が、収納凹部から直線的に延びて形成される。ラジアル折りの折畳部位56は、収納凹部の周囲で、直線状供給路の元部58aから先端部58cまでの間の中間部58bの周囲を囲むように、配設される。【選択図】図4
