To provide a gas producer which can be so controlled that while a cup body is increased in mechanical strength, a size of rupture of the cup body becomes stable.SOLUTION: A gas producer comprises: a short-sized cylindrical housing in which a gas producing agent is accommodated; an ignitor which includes an ignition part accommodating an ignition charge; and a cup-shaped member which includes an inflammation chamber accommodating a transfer charge thereinside and is formed of a single member in a bottomed cylindrical shape, in which a brittle portion which is partially thin is arranged at a top wall part of the cup-shaped member, and a side wall portion of the cup-shaped member is higher in mechanical strength than the brittle portion. The side wall portion of the cup-shaped member comprises a thin portion provided on the top wall part side and a thick portion extending from the thin portion to the opposite side from the top wall portion along an axial direction, in which the brittle portion has sufficient mechanical strength to rupture the cup-shaped member earlier than the side wall portion as the ignitor operates, and the thin portion has sufficient mechanical strength to rupture, deform, or melt when the brittle portion ruptures up to the thin portion.SELECTED DRAWING: Figure 1

    【課題】カップ体の機械的強度を高めつつも、カップ体の破裂の大きさが安定するように制御可能なガス発生器の提供。【解決手段】ガス発生剤が内部に収容された短尺筒状のハウジングと、点火薬が収容された点火部を含む点火器と、伝火薬が収容された伝火室を内部に含み、有底筒状の単一の部材からなるカップ状部材と、を備え、前記カップ状部材の頂壁部には一部に薄肉の脆弱部が配置され、前記脆弱部より機械的強度が高い前記カップ状部材の側壁部を備え、前記カップ状部材の側壁部には、前記頂壁部側に設けられた薄肉部と、前記薄肉部から軸方向に沿って頂壁部と反対側に延設された厚肉部と、を備え、前記脆弱部は、前記点火器の作動に伴って前記側壁部より先に前記カップ状部材を破裂する機械的強度を有したものであり、前記薄肉部は、前記脆弱部における破裂が前記薄肉部まで進展した場合、破裂、変形、又は溶融する機械的強度を有した、ガス発生器である。【選択図】図1
