First Claim
1. A gas generator for an air bag, comprising:
- a housing that stores a gas generating agent, said housing having upper and lower plate members and a wall member connecting said upper and lower plate members;
an igniter adapted to ignite said gas generating agent;
a coolant/filter adapted to cool and filter combustion gas generated by said gas generating agent;

Abstract
A gas generator is provided which is less likely to suffer from damages or peeling-off of a protruding seal tape during assembling of the generator, thus surely assuring a moisture preventive effect by the seal tape.
In the gas generator for an air bag, a recess is formed in a portion of a partition wall that divides a housing into an ignition means storage chamber that stores igniting means and a gas generating agent storage means that stores a gas generating agent, or in a portion of a housing, to which a seal tape is attached to close through-holes formed through the partition walls or housing. The depth and width of the recess are equal to or larger than the thickness and width of the seal tape. The seal tape is attached such that its side edge portions are received in the recess, so as to close the through-holes.
