PROBLEM TO BE SOLVED: To provide a gas generator capable of preventing actuation when output in a predetermined range is not performed by predetermined or higher humidity, and to provide a gas generator replacement time notification device using the gas generator.SOLUTION: A gas generator 100 has a short substantially cylindrical housing of which both ends in an axial direction are blocked, and is configured so as to store a holding section 30, an igniter 40, a cup-like member 50, a transfer charge 56, a gas generating agent 61, a lower side holding member 62, an upper side holding member 63, a cushioning member 64, a switch portion 80 and the like in a combustion chamber provided inside of the housing. The switch portion 80 is provided in the combustion chamber, and has a resin portion 81, a cantilever beam-like first energization member 82 of which one end is fixed to the resin portion 81, a cantilever beam-like second energization member 83 that has flexibility and of which one end is fixed to the resin portion 81, and a moisture sensitive member 84 having flexibility. The moisture sensitive member 84 is provided on an opposite side to the first energization member 82 of the second energization member 83.SELECTED DRAWING: Figure 1
【課題】所定以上の湿度によって予定範囲の出力が出せなくなった場合に作動を防止できるガス発生器と、該ガス発生器を用いたガス発生器交換時期報知装置を得る。【解決手段】ガス発生器100は、軸方向の両端が閉塞された短尺略円筒状のハウジングを有しており、このハウジングの内部に設けられた燃焼室内に、保持部30、点火器40、カップ状部材50、伝火薬56、ガス発生剤61、下側保持部材62、上側保持部材63、クッション材64、および、スイッチ部80等が収容されることで構成されている。スイッチ部80は、燃焼室内に設けられ、樹脂部81と、一端が樹脂部81に固定された片持ち梁の第1の通電部材82と、可撓性を有し、一端が樹脂部81に固定された片持ち梁の第2の通電部材83と、可撓性を有した感湿部材84と、を備えている。感湿部材84は、第2の通電部材83の第1の通電部材82と反対側に設けられている。【選択図】図1
