| abstract |
The present invention provides a gas generator in which an effect of decreasing the temperature of a combustion gas and an effect of capturing mist of the combustion gas are adjusted. n A cup member disposed in a cylindrical housing has one gas passage hole selected from a first gas passage hole, which is formed in part of a circumferential wall on the side of an opening, a second gas passage hole, which is formed in part of a circumferential wall on the side of a bottom portion, and a third gas passage hole, which is formed between the first gas passage hole and the second gas passage hole. By selecting one of the above gas passage holes, the effect of decreasing the temperature of the combustion gas and the effect of capturing mist of the combustion gas are adjusted. |
