A gas generator for a restraining device includes a housing formed by joining and integrating a diffuser shell having a gas discharge port and a closure shell, and a gas generating agent, an igniter, and a cylindrical filter, accommodated inside the housing. The housing has a top plate, a circumferential wall surface, and a bottom plate, and a plurality of protruding portions concaved inwardly and formed with a distance from each other on at least either of an upper annular corner portion located at a boundary portion between the top plate and the circumferential wall surface and a lower annular corner portion located at a boundary portion between the bottom plate and the circumferential wall surface. Part of the cylindrical filter is supported and fixed by the plurality of protruding portions, and a gap is provided between an outer circumferential surface of the cylindrical filter and the gas discharge hole.

The invention claimed is: 1. A gas generator for a restraining device, comprising: a housing formed by joining and integrating a diffuser shell having a gas discharge port and a closure shell, the housing accommodating, therein, a gas generating agent, an igniter, and a cylindrical filter; the housing having, a top plate, a circumferential wall surface, a bottom plate, and a plurality of protruding portions concaved inwardly, each protruding portion being formed discontinuously and formed independently from one another, the plurality of portions being formed in at least one of an upper annular corner portion located at a boundary portion between the top plate and the circumferential wall surface and a lower annular corner portion located at a boundary portion between the bottom plate and the circumferential wall surface, part of the cylindrical filter being supported and fixed to the housing by engaging with the plurality of protruding portions, and defining a gap between an outer circumferential surface of the cylindrical filter and the gas discharge hole. 2. The gas generator for a restraining device according to claim 1, wherein the plurality of protruding portions are formed in at least one of portions in the circumferential wall surface that is close to the top plate and the bottom plate. 3. The gas generator for a restraining device according to claim 1, wherein 2 to 10 protruding portions are formed equidistantly. 4. The gas generator for a restraining device according to claim 1, wherein a distal end portion of said each protruding portion has a curved surface protruding towards an inside of the housing.
