ABSTRACT:
By forming a resin sheet or a metal sheet, an angular-box-shaped bag main body (51) having gore portions (54) on surrounding side faces to ensure its height is formed. A folded line (55) to be folded, in a manner to form a valley line, toward an inside of the box-shaped bag main body (51) is formed in an intermediate portion of each of the gore portions (54) in a height direction. A triangular overlaid and folded portion (56) is formed in an end of each of the gore portions (54a) on each of the surrounding side faces with each corner portion of the angular-box-shaped bag main body (51) being sandwiched between one surrounding side face and another surrounding side face adjacent to the one surrounding side face in which the gore portion (54b) is folded in an overlaid manner in the overlaid and folded portion (56) at a same time when another gore portion on another surrounding side face is folded. The angular box-shaped bag main body (51) is folded so as to be in a flat state by allowing each of the gore portions to be folded in a manner to form a valley line along the folded line (55). By blocking a bottom face being opposite to a ceiling plate (52) with a bottom plate (53), the box-shaped bag main body (51) has a hermetically sealed structure. By configuring above, an inflator bag (50) for a vehicle occupant restraining apparatus is obtained. Thus, the inflator bag (50) is able to be housed in a compact manner and to be developed so as to be in a stable state with a sufficient developing stroke being ensured and able to be processed easily.
