Gas generator, gas generator holder and method for manufacturing gas generator holder

A gas generator comprising:

• a cup filled with a gas generating agent generating gas by combustion;
• an igniter arranged to face said gas generating agent and ignited at a time of working to burn said gas generating agent;
• and
• a holder made of metal with said cup and said igniter assembled thereto, wherein
• said holder includes a body part and a cup fixing engagement part projecting from said body part,
• said cup fixing engagement part is bent such that a part of said cup is sandwiched between said cup fixing engagement part and said body part, so that said cup is fixed by crimping to said holder, and
• said cup fixing engagement part is finish shaped by forging processing, so that a metal flow appearing in a superficial layer of said cup fixing engagement part extends continuously from said body part through said cup fixing engagement part to return to said body part, without being divided in a surface of said cup fixing engagement part.

A gas generator holder made of metal used with a cup filled with a gas generating agent and an igniter for burning the gas generating agent assembled thereto, comprising:

• a body part;
• and
• an igniter fixing engagement part projecting from said body part and being bent such that a part of the igniter is sandwiched between said igniter fixing engagement part and said body part, thereby fixing the igniter by crimping, wherein
• said igniter fixing engagement part is finish shaped by forging processing, so that a metal flow appearing in a superficial layer of said igniter fixing engagement part extends continuously from said body part through said igniter fixing engagement part to return to said body part, without being divided in a surface of said igniter fixing engagement part.
