PROBLEM TO BE SOLVED: To provide a method for generating a gas by which the flowing out of a working gas is rapidly and precisely carried out without requiring a returning spring for returning a movable member to an inoperable position, and further to provide an apparatus for generating the gas. SOLUTION: This gas-generating apparatus has a movable member 30 progressing by receiving explosion action of a detonation part 34 at the time of the operation of an airbag so as to oppose a passage-blocking plate 26 for blocking the passage for connecting a pressurized vessel storing the working gas to the airbag, and having a piercing part 33A penetrating the passage- blocking plate 26 at the tip part, arranged therein. The piercing part 33A has a shape regulated so that the passage of the gas may be kept in a state in which the piercing part 33A penetrates the passage-blocking plate. Concretely, the boring part 33A is formed into a cone shape having a maximum outer diameter larger than the shaft diameter of a shaft part 32, and an outer periphery surface in a wave shape. |
