Patent ID: 8573130

Claim:
A gas generator comprising: a housing body that houses a gas generating charge, the housing body being made from metal and generally tubular in contour; a squib that includes an igniter facing towards the gas generating charge for igniting the gas generating charge in order to generate a combustion gas and a pair of conductive pins extending generally along an axial direction of the housing body from the igniter; and a holder section that holds the squib and includes: a holder body made of metal and including an outer cylinder section that is generally tubular in contour and constitutes an outer circumferential region of the holder section, and a support section that protrudes inwardly from an entire inner circumference of the outer cylinder section in a continuous manner for supporting the igniter of the squib, the support section having a sectional contour that tapers towards a leading end thereof, the tapering occurring in the axial direction of the housing body as the sectional contour progresses inward toward the leading end; and a molded section that is located between the holder body and the squib and covered by the outer cylinder section of the holder body, the molded section being molded from synthetic resin to be integral with the holder body and the squib, and covering an outer surface of the support section allover and including: a set-in portion that holds the igniter and covers an outer circumference of the igniter generally all over in a closely contacting fashion except a region of the igniter facing towards the gas generating charge; and a cover section that is located on an opposite side of the set-in portion relative to the support section and generally tubular in contour, the cover section covering the conductive pins on an outside of the pins in a direction perpendicular to the axial direction of the housing body, wherein: the housing body includes an annular abutting portion facing toward the holder section for abutment against and coupling with the holder section; the molded section includes a flange at a location overlapping with the support section in the axial direction of the housing body and proximate the set-in portion; and the housing body is coupled with the holder section by coupling means that presses the annular abutting portion towards the holder section along the axial direction of the housing body so as to make a plane of the annular abutting portion facing toward the holder section abut against a plane of the flange facing toward the gas generating charge over entire circumferences.
