摘要： The invention provided a gas generator for an air bag having any of the following members. A deflecting member is provided to suppress discharge of a combustion product generated by a combustion of gas generating means, and is formed as a tube portion to be capable of shielding a gas discharge port formed at least on a circumferential wall of a housing from the inside of the housing. A coolant/filter means supporting member can position a coolant/filter means, prevent a short pass of an operating gas, and functions as a buffer member between the coolant/filter and the housing, and/or prevent a heat from being transferred to a diffuser shell, and comprises an annular portion arranged to face an end surface of the housing and a wall portion contacting with an inner periphery of the coolant/filter means. Further, in order to make it possible to securely support and fix the coolant means and prevent the short pass of the operating gas, an outer peripheral edge of an end portion thereof is adhered and/or supported to a bent portion or a step portion formed in an inner surface of an upper end surface and/or an inner surface of a lower end portion in the housing. The coolant/filter means is formed in a cylindrical shape obtained by laminating a wire mesh. The housing for the gas generator securely fixes an igniter included in an ignition means, is preferably used at a time of manufacturing a gas generator having a restricted overall height, and has an opening portion for inserting and fixing the igniter or an igniter supporting member. The opening portion is provided with a connecting portion for fixing the inserted igniter or igniter supporting member, and the connecting portion is provided in inner side of the housing rather than the end surface having the opening portion.

It is a gas generator for an air bag in which an inner cylindrical member is disposed in the housing to define an ignition means accommodating chamber and a combustion chamber, plural flame-transferring holes for communicating the both chambers with each other are formed on the circumferential surface of the inner cylindrical member, and the plural flame-transferring holes are formed at a distance of less than 30% of the axial length of the inner cylindrical member, from an end of the inner cylindrical member. A gas generator, which can use even a gas generating agent with less ignitability, and further can exhibit enough operation performance at the initial stage of activation even when using such a gas generating agent, is provided. It is a gas generator for an air bag in which an inner cylindrical member is disposed in the housing to define an ignition means accommodating chamber and a combustion chamber, and the central angle formed by the adjacent communicating portions which are formed on the circumferential surface of the inner cylindrical member is adjusted to be not more than 60 degrees.
