A new and improved single side wall air bag inflator includes a housing containing an ignition device, a quantity of pyrotechnic gas generant material and a filter. The housing includes a cup-shaped base member having an annular bottom wall with a central opening for access to the ignition device and an integrally formed, upstanding ported side wall extends upwardly of the bottom wall. The side wall has a radially inwardly deformable, free upper end portion forming a retaining flange for securing a top wall in place spaced above the bottom wall and closing off an upper end portion of the housing. The top wall has a depressed outer peripheral edge portion facing and sealed with the downwardly and radially inwardly deformed upper end flange of the single side wall.
