PROBLEM TO BE SOLVED: To seal gas even for a stream of gas which is directed toward an inflator cover by forming a pawl part which is protruded in the outward direction of radius from a basic part of a sleeve extension part and is hooked in an end part in the inside of a case of a fringe part of a case insertion hole. SOLUTION: A pawl part 18 is protruded in the outward direction of radius from a basic part of a sleeve extension part 17 and is hooked in an end part 11b in the inside of a case in a fringe part 11 of a case insertion hole. An inflator cover 12 is inserted into the case insertion hole 6 before an inflator 2 is inserted therein, a sleeve 13 adheres to the fringe part 11 of the insertion hole closely, the fringe part 11 of the insertion hole is nipped by a hook stepped part 14 and the pawl part 18 from the front and rear, and then the inflator 2 is inserted. The inward travel of the pawl part 18 is prevented by the inflator 2, and the inflator cover 12 is fixed on an air bag case. Consequently, it is possible to seal gas of the inflator 2 and seal gas even for a stream of gas G. |
