Abstract
The present invention provides an apparatus provided with an igniter assembly including: an igniter main body having an ignition portion, provided with an ignition agent, and an electroconductive pin, a resin portion surrounding at least part of the igniter main body and a substantially cylindrical igniter collar fixed to an outer surface of the resin portion, the igniter assembly being disposed in an opening formed in a bottom portion of a housing, the igniter collar of the igniter assembly being fixed to the housing, the igniter collar fixing to the resin portion y deforming the igniter collar so as to engage the igniter collar with a concave portion in the resin portion.
Claims6
An apparatus provided with an igniter assembly comprising:
- an igniter main body having an ignition portion, provided with an ignition agent, and an electroconductive pin;
- a resin portion surrounding at least part of the igniter main body, the resin portion including a concave portion formed in an outer circumference thereof;
- and
- a substantially cylindrical igniter collar fixed to an outer surface of the resin portion,
- the igniter assembly being disposed in an opening formed in a bottom portion of a housing,
- the igniter collar of the igniter assembly being fixed to the housing,
- the igniter collar being fixed to the resin portion by deforming the igniter collar radially so as to engage the igniter collar with the concave portion in the resin portion.
A method of assembling an apparatus provided with an igniter assembly, comprising
- inserting an intermediate body including an igniter main body and a resin portion and having a concave portion in a circumferential surface of the resin portion, into a substantially cylindrical igniter collar integrated with the housing;
- and
- applying pressure to a portion of an outer circumferential surface of the igniter collar that directly opposes the concave portion of the resin portion to cause deformation into a shape matching that of the concave portion of the resin portion, and fixing the resin portion to the igniter collar.
