PURPOSE: To form an air bag in such a way that the thickness of a part of the airbag, which corresponds to a part of a hood, which can absorb the shock by deforming itself, becomes thin. CONSTITUTION: The thickness of an airbag 16 when expanded is such that the central part 16a of the airbag 16, which corresponds to a part of a hood 15 whose lower side is provided with a space allowing the hood 15 to deform downward thereby absorbing the shock through deformation, becomes thiner than the thickness of the side edge part 16b and a rear edge part 16c of the airbag 16, which do not correspond to the part of the hood 15 provided with the said space. In this way, since the volume of the airbag 16 can be reduced without imperiling the pedestrians protecting function, the volume of the gas required for expanding the airbag 16 can be reduced, while the time required for expanding can be shortened. |
