PROBLEM TO BE SOLVED: To prevent entering of moisture from an inflammation hole by exploding a part of a structure for mounting detonator by explosive combustion of the detonator stored/fixed within a recess and burning inflammation chemical by flame in which the detonator burns. SOLUTION: When a sensor 6 senses impact, a firing pin 18 in the sensor 6 is fired and a detonator 10 stored/fixed within a recess 17 of a detonator piece 11 is stuck, in a gas generator. When the detonator 10 is stuck with the firing pin 18, the detonator 10 explosively burns with the energy, explodes the bottom part of the detonator piece 11 sectioning an inflammation chemical storing chamber and a sensor storing chamber and makes both of the storing chambers be communicated. Flame in which this detonator burns ignits inflammation chemical stored within an inflammation chemical storing chamber and burns the chemical and the flame burns gas generation agent 13 by passing through a through hole 20 and generates gas. An aluminum tape 16 is stuck to the opening of the recess 17 storing the detonator 10 and moisture absorption of the detonator 10 from the direction of the sensor 6 is prevented. |
