To provide a technique to suppress short pass in a gas generator while having a constitution to be easily assembled.SOLUTION: A gas generator includes: an ignition device arranged inside a housing; a cylindrical filter where an opening is formed at least at one end part of both end parts, and which includes a burning chamber filled with a gas generating agent burned by the ignition device in the inside; a gas discharging port which is provided in the housing in a manner that a filter is positioned between the burning chamber and the gas discharging port for communicating the inside of the housing with the outside; and a cushion member which is formed of a material that is elastically deformed or plastically deformed and applies biasing force to the gas generating agent filled in the burning chamber. The cushion member has at least one part of an outer peripheral part that is tightly held between a first wall part and one end part of the filter for the whole periphery and is arranged in a state in which an inner region of the cushion member enclosed by the peripheral part makes contact with the gas generating agent filled in the burning chamber.SELECTED DRAWING: Figure 2
【課題】ガス発生器において、組み立て容易な構成としつつ、ショートパスを抑制し得る技術を提供する。【解決手段】ガス発生器は、ハウジング内に配置された点火装置と、両端部のうち少なくとも一端部に開口が形成され、その内部に点火装置により燃焼されるガス発生剤が充填される燃焼室を含む、筒状のフィルタと、燃焼室との間にフィルタが位置するようにハウジングに設けられ、ハウジングの内部と外部とを連通するガス排出口と、弾性変形又は可塑変形する材料で形成され、燃焼室に充填されたガス発生剤に対して付勢力を付与するクッション部材と、を備えている。クッション部材は、その外周部の少なくとも一部がその一周にわたって第1壁部とフィルタの一端部との間に挟持され、外周部で囲まれたクッション部材の内領域が燃焼室に充填されたガス発生剤と接触した状態で配置される。【選択図】図2
