An inflator and airbag are fixed by a fixing member including a lower fixing member that supports and fixes the inflator from a lower surface side of a plate portion. The lower fixing member has a tubular wall portion and a flange portion formed at an opening at one end. The tubular wall portion has an inner surface in a shape that is fitted to a circumferential wall surface, including a lower annular step surface, of the inflator housing. The flange portion has a plurality of bolt holes and abuts against a lower surface of the plate portion. The airbag and the lower fixing member are fixed with a bolt and a nut mounted through the airbag, the plate portion, and the flange portion of the lower fixing member.

1. A fixing structure for an inflator and an airbag, in which the inflator and the airbag are fixed by two fixing members to a plate portion of a module case, comprising an outer shell of the inflator being a housing in a substantially columnar shape,the housing including a gas discharge port provided in a circumferential wall surface on one end of the housing in the axial direction, andan upper annular step surface and a lower annular step surface provided at circumferential wall surfaces of the outer shell on upper and lower ends thereof, respectively, in the axial direction, the upper annular step surface and the lower annular step surface being formed by reducing an outer diameter of the housing on the respective ends,the two fixing members being an upper fixing member that supports and fixes the inflator from an upper surface side of the plate portion, and a lower fixing member that supports and fixes the inflator from a lower surface side of the plate portion, the upper fixing member including an annular flat portion provided with a plurality of bolt holes, and an annular outer circumferential wall portion extending vertically from an outer circumference of the annular flat portion,the lower fixing member including a tubular wall portion and a flange portion formed at an opening at one end,the tubular wall portion having an inner surface in such a shape that the tubular wall portion is fitted to the circumferential wall surface including the lower annular step surface of the inflator housing, andthe flange portion having a plurality of bolt holes,the fixing structure for the inflator and the airbag including the inflator fitted into a hole, which is formed in the plate portion of the module case, such that the circumferential wall surface provided with the gas discharge port is on an upper surface side of the plate portion, and the circumferential wall surface including the lower annular step surface is on a lower surface side of the plate portion,on the upper surface side of the plate portion, the airbag covering and enclosing, from a bag opening, the circumferential wall surface provided with the gas discharge port, of the inflator housing,on the upper surface side of the plate portion, the upper fixing member fitted to the inflator housing such that the annular flat portion abuts against the plate portion, with the airbag being interposed therebetween, and an inner circumference of the annular flat portion abuts against the upper annular step surface,on the lower surface side of the plate portion the lower fixing member having the tubular wall portion abutting against the circumferential wall surface, which includes the lower annular step surface of the inflator housing, and the flange portion abutting against the lower surface of the plate portion, andthe upper fixing member, the airbag and the lower fixing member being fixed with a bolt and a nut mounted through the upper fixing member, the airbag, the plate portion, and the flange portion of the lower fixing member. 2. The fixing structure for an inflator and an airbag according to claim 1, wherein at least one of said fixing members is formed of a metal that is the same as a metal forming the inflator housing, and the thickness of said at least one of said fixing members is less than the thickness of the inflator housing. 3. The fixing structure for an inflator and an airbag according to claim 1, wherein at least one of said fixing members is formed of a metal that is different from a metal forming the inflator housing, and the metal forming said at least one of said fixing members is less in specific gravity than the metal forming the inflator housing. 4. The fixing structure for an inflator and an airbag according to claim 1, wherein at least one of said fixing members is formed of a resin or a composite including a resin.
