To provide a technique which, in an igniter assembly having such a structure that an igniter is surrounded by a resin peripheral wall part, can inhibit a large load from being applied to the peripheral wall part by a lid wall part of a cup body ruptured upon actuation of the igniter.SOLUTION: An igniter assembly X1 includes: an igniter 40 which includes a metal storage container including a cylindrical peripheral wall part 11 and a lid wall part 12 closing one end part of the peripheral wall part 11, and an ignition charge 3 packed in a storage space defined by the peripheral wall part 11 and the lid wall part 12, and which releases a combustion product of the ignition charge 3 to the outside of the storage container due to the rupture of the lid wall part 12 upon actuation; and a resin cylindrical wall part 60 formed in a cylindrical shape so as to surround the peripheral wall part 11, and forming therein a release space into which the combustion product of the ignition charge is released. The lid wall part includes: an annular outer peripheral region part 121 connected to the one end part of the peripheral wall part; and a central region part located on an inner side in the radial direction of the peripheral wall part 11 relative to the outer peripheral region part. The outer peripheral region part is formed to be thicker than the central region part 122.SELECTED DRAWING: Figure 3

    【課題】樹脂製の周壁部で点火器を取り囲む構造の点火器組立体において、点火器の作動時に開裂したカップ体の蓋壁部によって周壁部に大きな荷重が作用することを抑制できる技術を提供する。【解決手段】点火器組立体X1は、筒状の周壁部11と周壁部11の一端部を閉塞する蓋壁部12とを有する金属製の収容器と、周壁部11と蓋壁部12とによって画定される収容空間に充填された点火薬3と、を含み、作動時に蓋壁部12が開裂することにより点火薬3の燃焼生成物を収容器の外部に放出する点火器40と、周壁部11を取り囲むように筒状に形成され、点火薬の燃焼生成物が放出される放出空間を内側に形成する樹脂製の筒状壁部60と、を備え、蓋壁部は、周壁部の一端部に接続される環状の外周領域部121と、外周領域部よりも周壁部11の径方向における内側に位置する中央領域部と、を含み、外周領域部は、中央領域部122よりも厚肉に形成されている。【選択図】図3
