To provide an igniter which suppresses inhibition of fire transfer to a transfer charge by adjusting elongation of a cup-shaped member during operation while holding sealability and insulation property, and a gas generator.SOLUTION: A disk type gas generator 100 has a short-length and substantially cylindrical housing of which one end and the other end in an axial direction are blocked, and in a storage space provided in the housing, a holding part 30 as an internal component, an igniter 40 with a squib cover 43, a cup-shaped member 50, a transfer charge 59, a gas generating agent 61, a lower side support member 70, an upper side support member 80, a cushioning material 85, a filter 90 and so on are accommodated. The squib cover 43 is configured in such a manner that a thermosetting resin or a thermoplastic resin containing an elongation adjustment material is molded into a cup shape so that an elongation rate when operating the igniter 40 becomes more than 0% and less than 10%.SELECTED DRAWING: Figure 1
【課題】シール性および絶縁性を保持しつつも、カップ状部材の作動時の伸びを調整して伝火薬への伝火の阻害を抑制した点火器、および、ガス発生器を得る。【解決手段】ディスク型ガス発生器100は、軸方向の一端および他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収容空間に、内部構成部品としての保持部30、スクイブカバー43を有した点火器40、カップ状部材50、伝火薬59、ガス発生剤61、下側支持部材70、上側支持部材80、クッション材85およびフィルタ90等が収容されてなるものである。スクイブカバー43は、点火器40の作動時における伸び率が0%より大きく10%未満となるように、熱硬化性樹脂または熱可塑性樹脂に伸び率調整材を含有させたものをカップ状に成型してなるものである。【選択図】図1
