<P>PROBLEM TO BE SOLVED: To provide a gas generator capable of preventing a blocking member from scattering during actuation. <P>SOLUTION: In the gas generator 10, the blocking member 11 is arranged so as to couple a peripheral edge to an outer peripheral wall 23 side in a housing 22, and block an outflow hole 25 formed on a ceiling wall 24 of the housing 22. In the blocking member 11, a thin-wall break estimating portion capable of breaking when a squib 19 is actuated is formed in a linear shape generally radially extending from a center. When the squib 19 is actuated, the break estimating portion breaks, and parts between the break estimating portions in the blocking member 11 are configured to radially open as door portions. On a surface on the blocking member side on the ceiling wall 24, a stopper portion 26 abutting the opening door portions so as to ensure an opening angle capable of flowing out combustion gas and make the opening angle of the door less than 90°. <P>COPYRIGHT: (C)2010,JPO&INPIT |
