摘要： A gas generator including a cup filled with gas generant molded articles that generate gas by combustion, and an ignitor on which an ignition agent is disposed. Each gas generant molded article is formed of smokeless powders containing nitrocellulose as its major ingredient. Each gas generant molded article includes an explosive containing a fuel agent containing a guanidine derivative and/or a tetrazole derivative and an oxidizing agent containing a metal nitrate and/or perchlorate. Thus, it is possible to provide a gas generator by which the amount of CO gas generated in operation can be reduced and the combustion speed can easily be controlled, and to provide a pretensioner system provided with the gas generator.
