An inflator ( 14 ) includes a structure ( 50, 70, 90 ) that helps define a chamber ( 42 ) from which inflation fluid flows. The structure ( 50, 70, 90 ) includes an end cap ( 90 ) having a side wall ( 92 ). A closure member ( 104 ) is rupturable to release inflation fluid from the chamber ( 42 ). An initiator ( 230 ) is actuatable to rupture the closure member ( 104 ). A filter retainer ( 170 ) includes a side wall ( 172 ) that defines a cavity ( 176 ). The side wall ( 172 ) of the filter retainer ( 170 ) includes a rim portion ( 196 ) that forms a terminal end of the side wall. A filter assembly ( 120 ) is positioned in the cavity ( 176 ) of the filter retainer ( 170 ). First segments ( 260 ) of the rim portion ( 196 ) are deformed to clamp the filter assembly ( 120 ) to the filter retainer ( 170 ). Non-deformed second segments ( 262 ) of the rim portion ( 196 ) engage an inner surface ( 264 ) of the side wall ( 92 ) of the end cap ( 90 ). The second segments ( 262 ) help position the end cap ( 90 ) and the filter retainer ( 170 ) coaxially with each other.
