Abstract
Stud bolts 51, 52 are fixed by welding to the side faces of a first closure 30 and a second closure 40, which are connected to a cylindrical housing 20. When connecting a gas introduction port of the air bag to a diffuser portion 43, the stud bolts 51, 52 do not cause an obstruction, and hence the attachability of an inflator 10 to a module case using the stud bolts 51, 52 is not impaired.
