PROBLEM TO BE SOLVED: To simplify a gas leak preventing structure and a bag fixing structure by boring an insertion hole, and providing a closing fabric closely covering a bag from both outside and inside faces. SOLUTION: The closure section 32 of a closing fabric 3 is lifted, and one portion of a ground fabric 11 including one side of a slit (insertion hole) 12 located on the inside of the closure section 32 is temporarily removed from the closure section 32 so that the slit 12 is not covered by the closure section 32. The closure section 32 and reinforcement section 31 are lifted together with the closing fabric 3, and the slit 12 of a bag 1 is spread and opened. A tubular inflator is inserted into the bag 1 from the opened slit 12. The slit 12 is closed in the opposite order, and the closure section 32 is returned to the original state to cover the slit 12. A protruded fitting section provided on the inflator is inserted into the fitting hole 15 of the bag 1 and the fitting hole 33 of the closing fabric 3, and the fitting section is protruded to the outside of the bag 1. |
