Abstract
A gas generator includes a lower shell as a housing, an igniter including a squib cup and a plug, and a fixing portion formed from a resin molding for fixing the igniter to the lower shell. The squib cup includes a contact portion in contact with the plug and a non-contact portion not in contact with the plug. The fixing portion includes a cover portion secured to an outer circumferential surface of the squib cup, and the cover portion has a lower-side annular cover portion covering a part of the contact portion and an upper-side annular cover portion covering a part of the non-contact portion. A thickness t2 of the upper-side annular cover portion is smaller than a thickness t1 of the lower-side annular cover portion, and the cover portion is formed in a stepped shape having a substantially two-dimensionally annular step-formed surface orthogonal to an axial direction of the squib cup.
