PURPOSE:To reduce the capacity of a combustion chamber greatly by constructing each gas generating agent in the form of a ring-shaped plate provide in the center with a through hole, laminating this gas generating agent, and putting an ignitor and firing powder in through hole provided in the center. CONSTITUTION:Five or six sheets of gas generating agent 43 are arranged outside of firing powder 47 and an ignitor 45 in a combustion chamber 41, wherein each gas generating agent 43 is made in the form of a ring-shaped plate provided in the center with a through hole 44. Separators 83 are arranged between the sheets of gas generating agent, wherein each separator 83 consists of a ring-shaped gold steel using a stainless steel wire of #10-50, wherein the firing characteristic of the gas generating agent 43 is enhanced to enable securing an exhaust passage for the gas generating agent 43. When current is supplied to an ignitor 45 and the powder 47 is fired, the gas generating agent 43 will combust to generate combustion gas. This constitution reduces the rate of voids greatly compared with the case in which the combustion chamber is filled with a number of pellets of gas generating agent. |
