Abstract:
A method of manufacturing an airbag gas generator including a housing having a diffuser shell provided with a gas discharge port, comprising;providing an inner cylindrical member having a peripheral wall, said inner cylindrical member having open ends; bending the peripheral wall at a portion adjacent to one of the open ends to form a flat surface that extends at an angle with respect to the peripheral wall; placing said inner cylindrical member onto an inner surface of the diffuser shell such that the flat surface is in contact with the inner surface; attaching said inner cylindrical member to an inner surface by welding said flat portion and the diffuser shell; providing a plate member around said inner cylindrical member, the plate member including a first circular portion defining a central hole and a circumferential wall portion formed at an outer edge of the first circular portion; positioning said plate member by engaging said central hole with at least one of the peripheral wall and an outer circumference of said flat portion; providing a cylindrical coolant member for at least one of cooling and filtering combustion gas generated when the gas generator operates; and positioning said cylindrical coolant member by engaging an inner circumferential surface of said cylindrical coolant member with an outer circumference of the circumferential wall portion.
