PROBLEM TO BE SOLVED: To fix an ignitor to a gas-generator side while maintaining the inside of a gas generator in an appropriately sealed state without using an ignitor collar.SOLUTION: A fixing structure comprises: an electric ignition type ignitor for a gas generator, the ignitor having an ignition part containing ignition agent, a base part formed of resin and covering at least a part of the periphery of the ignition part, and an electric conduction part that electrically conducts the ignition part; and a metal housing having: a cylindrical peripheral wall part defining an accommodating space for the ignitor; and a basal part extending radially inside the peripheral wall part from one end of the peripheral wall part so as to define a through- hole through which the electric conduction part can extend outward in the accommodating space when the ignitor is disposed in the accommodating space. The peripheral wall part is plastically deformed in contact with the base part toward a side-surface side of the base part opposite to the internal wall surface of the peripheral wall part such that the ignitor is disposed in the accommodating space of the housing, the base part is pressed against the internal wall surface of the basal part, and a predetermined sealed state is formed between the ignitor and the housing.SELECTED DRAWING: Figure 4

    【課題】点火器カラーを用いずにガス発生器内を好適なシール状態に維持しながら点火器をガス発生器側に固定する。【解決手段】着火薬を含む着火部と、該着火部の周囲の少なくとも一部を覆う樹脂で形成されたベース部と、該着火部へ通電する通電部とを有する、ガス発生器のための電気着火式の点火器と、点火器の収容空間を画定する筒状の周壁部と、該収容空間内に該点火器が配置されたときに通電部が該収容空間の外側に向かって延在可能となる通過孔を生成するように該周壁部の一方の端部から該周壁部の半径方向内側に延出する基部とを有する金属製のハウジングと、を備える固定構造であって、点火器がハウジングの収容空間内に配置され、ベース部が基部の内壁面に押圧されて、該点火器と該ハウジングとの間に所定のシール状態が形成されるように、周壁部の内壁面と対向する該ベース部の側面側に向かって、該周壁部が塑性変形されて該ベース部に接触している。【選択図】図4
