INITIATOR ASSEMBLY
First Claim
1. An initiator assembly, comprising:
- an electric type initiator;
a metallic collar surrounding at least part of the electric type initiator, said metallic collar including a cylindrical protrusion extending towards said electric type initiator in an axial direction of the metallic collar and a concavo-convex portion formed on an inner surface of the cylindrical protrusion; and
a resin injected between said electric type initiator and said metallic collar such that said metallic collar is integrally molded with the resin and the resin makes contact with the concavo-convex portion.

Abstract
The present invention provides an initiator assembly in which a metallic collar and an electric type initiator are combined securely to block a moisture penetration into the inside of the gas generator, thereby obtaining operation reliability of the gas generator.
An initiator assembly in which an electric type initiator and a metallic collar surrounding at least part of the electric type initiator are integrated with a resin, wherein at least either of an annular protrusion and a cylindrical protrusion provided in the direction to surround the electric type initiator is formed on the metallic collar, and the protrusion is covered with the resin.
