PROBLEM TO BE SOLVED: To provide a hollow-woven air bag in which inner-pressure retaining performance is improved by restricting aperture in the boundary between each bag part and a closing part.SOLUTION: A hollow-woven air bag 1 comprises, in the following order arranged from the center side to the outer side of the bag 1: a first bag part 11 rendered expandable by allowing a gas to flow into a space between two separable fabric layers 111, 112; a first inversion texture 21 adjacent to the outer periphery of the first bag part 11 and formed by crossing and inverting the respective compositional yarns of the fabric layers 111, 112; a second bag part 12 having two fabric layers 121, 122, separably woven using compositional yarns crossed and inverted in the first inversion texture; a second inversion texture 22 formed by crossing and inverting the respective compositional yarns of the fabric layers 121, 122; a third bag part 13 having two fabric layers 131, 132 separably woven using compositional yarns crossed and inverted in the second inversion texture; and a closing part 31 formed in such a manner that the respective compositional yarns of the fabric layer 131, 132 are woven in single layers.SELECTED DRAWING: Figure 1 |
