A vehicle safety apparatus (10, 10a) for helping to protect a vehicle occupant during a vehicle collision above a predetermined threshold. The apparatus (10, 10a) includes a reaction canister (14, 14a), an inflatable vehicle occupant protection device (16) located in the reaction canister, and an inflator (18, 18a) for supplying inflation fluid to inflate the vehicle occupant protection device. The reaction canister (14, 14a) has a main body portion (20), a first end wall (24) and a second end wall (26, 26a) opposing the first end wall. The first and second end walls (24, 26, and 26a) are fixed to the main body portion (20) and define a chamber (40). The first end wall (24) has an inner surface (46) and an outer surface (48). A first opening (52) having a first diameter is formed in the first end wall. The inflator (18, 18a) has a cylindrical body portion (82, 82a) having a first end (86) and a second end (90, 90a) opposite the first end. A flange member (130) is fixed to the first end (86) of the inflator (18, 18a). The inflator (18, 18a) is axially insertable through, the first opening (52), into the chamber (40). The flange member 130 is clamped against the outer surface (48) of the first end wall (24). The inflator (18, 18a) is supported on the second end wall (26, 26a).
