A gas generator is formed of a container having an outer-shell member, and a partition member disposed at least partly inside the outer-shell member to thereby form a plurality of chambers inside the container and fixed to the outer-shell member, a fixation area increasing portion formed at at least one of the partition member and the outer-shell member, a gas generating agent disposed inside the plurality of chambers of the container, and an igniter for igniting the gas generating agent. The gas generator reliably prevents the gas leak from a portion of fixation of the outer-shell member and the partition member.

1. An airbag device comprising:an air bag;a gas generator for generating gas for expanding the airbag comprising:a container including an outer-shell member with an opening, and a partition member disposed at least partly inside the outer-shell member to form a plurality of chambers inside the container and fixed to the outer-shell member, said partition member having one end fixed to an inside surface of the outer-shell member and the other end passing through and extending outward from the opening of the outer-shell member,a fixation area increasing portion formed of an annular portion provided at the outer-shell member to protrude inwardly of the outer-shell member for defining the opening and having an inner edge, said annular portion fitting onto the partition member for increasing connection between the outer-shell member and the partition member,a gas generating agent disposed inside the plurality of chambers of the container,an igniter disposed in the partition member for igniting the gas generating agent, andan annular squib holder located inside the partition member to support the igniter thereon and face the fixation area increasing portion of the outer-shell member, said squib holder having an upper edge contacting the partition member which is substantially located in a horizontal level where the inner edge of the annular portion is located so that the squib holder and the annular portion sandwich the partition member therebetween to securely hold and support the partition member; anda module cover for covering the airbag. 2. An airbag device according to claim 1, wherein an inner peripheral surface of the annular portion for defining the opening of the outer-shell member and an outer peripheral surface of the tubular partition member are fixed together. 3. An airbag device according to claim 2, wherein the inner peripheral surface defining the opening of the outer-shell member and the outer peripheral surface of the partition member are welded together. 4. An airbag device according to claim 1, further comprising an enhancer cup disposed between the squib holder and the inside surface of the outer-shell member inside the partition member.
