To fix a gas generating agent to be filled into an ignition device within a cylinder inner member.SOLUTION: An ignition device 61 includes: an igniter 41; a cylinder member 51 for defining a space into which a gas generating agent 54 to be burnt by the igniter 41 is filled, the cylinder member 51 including a cylindrical peripheral wall part 511 and a top face part 512 for blocking one end 51b of the peripheral wall part 511 and storing the igniter 41 in an other end 51c of the peripheral wall part 511. A diameter change part 10 in which an internal diameter of the peripheral wall part 511 is smaller or larger than the one end 51b and the other end 51c is formed between the one end 51b and the other end 51c in a center axis direction of the cylinder member 51 in the peripheral wall part 511 of the cylinder member 51. The gas generating agent 54 is filled not only on a side of the one end 51b but also on a side of the other end 51c relative to the diameter change part 10 inside the cylinder member 51 while coming into contact with the diameter change part 10.SELECTED DRAWING: Figure 1
【課題】点火装置に充填されるガス発生剤を筒内部材内で固定する。【解決手段】点火器41と、点火器41により燃焼されるガス発生剤54が入る空間を画定する筒部材51であって、筒状の周壁部511及び周壁部511の一端51bを閉塞する頂面部512を有し、周壁部511の他端51cに点火器41を収容する筒部材51と、を備える、点火装置61であって、筒部材51の周壁部511には、筒部材51の中心軸方向の一端51bと他端51cとの間において、周壁部511の内径が、一端51b及び他端51cよりも小さい又は大きい径変化部10が形成され、径変化部10に接触してガス発生剤54が筒部材51の内部で、径変化部10に対して一端51bの側にも他端51cの側にも充填されている。【選択図】図1
