<p>PROBLEM TO BE SOLVED: To accurately hold an igniter while reducing a cost.SOLUTION: A disc-shaped gas generator 100 has a base plate 1 and an under plate 3. The base plate 1 has a generally circular projecting portion 11 which is integrally equipped with a first flat plate portion 13, and a generally cylindrical outer cylinder portion 15 for supporting a radial outer peripheral end of the first flat plate portion 13, by press molding; and an igniter attaching portion 90 which is equipped with a second flat plate 14, a generally cylindrical inner cylinder portion 17 extending from a radial inner peripheral end of the second flat plate portion 14 to an axial direction the other side, and an abutting portion 19 provided so as to project out from the axial direction the other side end portion of the inner cylinder portion 17 to radially inside, by press-molding, and has a smaller diameter than the circular projecting portion 11. The second flat plate portion 14 of the igniter attaching portion 90 is fixed on a lower side of the first flat plate portion 13 of the circular projecting portion 11, thereby positioning an igniter 9 from radially outside with the abutting portion 19 integrally provided on the igniter attaching portion 90.</p> |
