Abstract
At the time of manufacturing an inflator, a blocking body is first disposed at an opening so as to allow the interior and the exterior of a housing to communicate with each other. The blocking body is abutted against a peripheral edge of the opening so as to ensure sealability between the blocking body and the peripheral edge of the opening. A filling nozzle injecting a pressurized gas is then pressed against a periphery of an inlet port of the blocking body, and the pressurized gas is injected from the filling nozzle so as to fill the pressurized gas into the housing through a filling channel. Subsequently, to block the filling channel, the blocking body is energized with a resistance-welding current to resistance-weld an inner peripheral portion of the filling channel. At the same time, the blocking body is fixed to the peripheral edge of the opening by resistance-welding so as to maintain sealability, thereby manufacturing the inflator.
