Abstract: The present invention relates to a gas generating agent composition containing pentaerythritol, perchlorate and a water-soluble polymeric binder agent. The gas generating agent composition may provide a gas generating agent excellent in heat resistance and anti-hygroscopicity. A gas generator which is loaded with the gas generating agent composition is preferably applicable as a gas generator for activating vehicle safety devices installed on the exterior of the vehicle. This may improve the reliability of vehicle safety devices.

Abstract: A metal holder, and a method of producing the same, with electrode pins suitably used for a gas generator having a structure that can prevent electrode pins from being burst forth easily even when the gas generator is brought into action under high temperature. The metal holder with electrode pins includes a metal holder and at least two electrode pins for allowing passage of electrical current. Each electrode pin is larger in diameter at its head portion than at its terminal portion. Plastic members are arranged to surround a part of the respective electrode pins circumferentially. Holes for the respective electrode pins to pass through the holder are formed in the holder, and the electrode pins are fixed to the holes via the plastic members, each hole having a diameter-reduction portion at a part thereof.
