PURPOSE: To reduce the risk of rupture of a container and maintain a distance between an igniting charge and an ignitor by forming an igniting charge storing projected part on the end surface of a cylindrical pack of a cylindrical member, fitting a heat transfer member pressed on an end plate part on the other side by an energizing member closely onto the projected part, and integrally forming a spring part on the end plate side located on the other side of the close-fitted part. CONSTITUTION: A gas generating agent pack 51 stored in an outer cylindrical member 35 is provided with a cylindrical pack 53, igniting charge 64 is arranged on one side of it, and a projected part 68 for storing igniting charge 66 is installed at the center of a cap 61 on the other side. Also a heat transfer member 9 which is pressed toward an end plate part 30 on the other side by an energizing member 89 and on which a spring part is installed is fitted closely onto the projected part 68. Electric current flows through an ignitor 85, the igniting charge 64 is burned, and gas generating agent 57 is burned by the igniting charge 66 on the other side. Because the container is ignited by fire at a lower temperature than the igniting temperature of firing agent 57 contained in gas generating agent 57, it becomes difficult for the container to be burst In addition, because one side end surface 59 is pressed toward a one side end plate part 37 in which the ignitor 85 is stored, an interval between the igniting charge 64 and the ignitor 85 is securely maintained.
