PROBLEM TO BE SOLVED: To effectively prevent falling and moving of igniting chemical by directly press filling chemical ignited by being stuck with a firing pin fired from a sensor at the time of sensing impact within a recess formed in a structure for storing chemical such as a chemical storing piece. SOLUTION: A chemical storing piece 11 is formed as a body separated from a housing 1 and is disposed within an ignition means storing chamber 8. In the direction of a sensor 6 of the chemical storing piece 11, a cylindrical recess 17 is formed on the extension line of the direction in which the firing pin 18 of the sensor 6 is fired. Within the recess 17, chemical 10 is press filled and fixed. In this recess 17, an inflammation hole 20 which is communicated with a chamber storing inflammation chemical 12 and a chamber storing the sensor 6 is formed on the bottom surface. This inflammation hole 20 is clogged with a seal tape 21. A gap part 5 punched by an inner diameter which is larger than the recess 17 is formed around the recess 17. |
