An airbag is quickly inflated and deployed along an inner side wall of a vehicle while suppressing variations of the deployment direction of the airbag inflated and deployed from an upper part of the vehicle. An upper edge side of an airbag (2), which deploys first, is bellows-folded to form a bellows portion (2J), and a lower edge side continuous with the bellows portion (2J) is roll-folded toward the vehicle's exterior side (G) to form a roll-folded portion (2R). The roll-folded portion (2R) is formed to have a larger width than the bellows portion (2J) in the vehicle's width direction and the both sides thereof are folded back upward. The bellows portion (2J) is folded in substantially half and is wrapped by the roll-folded portion (2R) from below and is accommodated therein. When the airbag (2) deploys, first, the bellows portion (2J), whose deployment is restricted by the roll-folded portion (2R) on both sides, deploys toward the lower side of the vehicle, and the roll-folded portion (2R) is pushed by the deployment force thereof toward the trim (50) and opens the trim (50), through which the roll-folded portion (2R) pops out and deploys in the vehicle. |
