PROBLEM TO BE SOLVED: To provide a gas generator which unfailingly prevents gas leakage during operating time and crush of a gas generating agent during non-operating time and is easily manufactured at lower costs.SOLUTION: A gas generator 1A includes: a housing including a top plate part 21 and a bottom plate part 11; a cylindrical filter 90; a gas generating agent 61 composed of particulate moldings; and a metal pressing member 80A. The pressing member 80A has: a first contact part 81 configured to contact with the filter 90 and having a cylindrical plate shape; a second contact part 82 configured to contact with a substantially center part of the top plate part 21; and a connection part 83 which connects the first contact part with the second contact part and has an annular plate shape. The connection part 83 includes a plate spring part 84 which is formed so that a distance from the top plate part 21 gradually increases from the second contact part 82 to the first contact part 81. A part of the gas generating agent 61 is stored in a storage space 89 defined by the second contact part 82 and the plate spring part 84. The structure allows the plate spring part 84 to elastically bias the gas generating agent 61.SELECTED DRAWING: Figure 1 【課題】作動時におけるガスの漏れ出しと非作動時におけるガス発生剤の破砕とが確実に防止でき、さらにはより安価にかつ容易に製造することができるガス発生器を提供する。【解決手段】ガス発生器１Ａは、天板部２１および底板部１１を含むハウジングと、筒状のフィルタ９０と、複数の粒状成形体からなるガス発生剤６１と、金属製の押さえ部材８０Ａとを備える。押さえ部材８０Ａは、フィルタ９０に当接する筒板状の第１当接部８１と、天板部２１の略中央部に当接する第２当接部８２と、これらを接続する環状板形状の接続部８３とを有する。接続部８３は、第２当接部８２から第１当接部８１に向かうにつれて天板部２１との間の距離が漸増する板バネ部８４を含む。ガス発生剤６１の一部は、第２当接部８２と板バネ部８４とによって規定される収容空間８９に収容され、これにより板バネ部８４によってガス発生剤６１が弾性付勢される。【選択図】図１
