Publication number: 20230202422Abstract: A gas generator includes an igniter assembled to one end portion of a housing, a gastight container arranged in the inside of the housing, and a coil spring interposed between the one end portion of the housing and the gastight container. The gastight container melts or bursts as a result of activation of the igniter. A gas generating agent is accommodated in the gastight container. The coil spring serves to fix the gastight container in the inside of the housing. The coil spring is arranged substantially coaxially with an ignition portion to surround the ignition portion without interposition of another member between the coil spring and the ignition portion, so as to restrict a degree of opening of a cup body included in the ignition portion of the igniter at the time of cleavage of the cup body.Type: ApplicationFiled: April 13, 2021Publication date: June 29, 2023Applicant: NIPPON KAYAKU KABUSHIKI KAISHAInventor: Yuji INOUE
