PCT No. PCT/JP95/00900 Sec. 371 Date Jan. 7, 1997 Sec. 102(e) Date Jan. 7, 1997 PCT Filed May 11, 1995 PCT Pub. No. WO95/31356 PCT Pub. Date Nov. 23, 1995A gas generator for an air bag, including a combustion chamber and a hermetic container accommodated in the combustion chamber. Gas generant pellets are charged in the hermetic container. The hermetic container has a wall adapted to be destroyed during combustion of the gas generant pellets. A partition foil piece covers a surface formed by the gas generant pellets charged in the hermetic container so as to conform to a profile of the surface formed by the gas generant pellets. The partition foil piece is non-reactive with the gas generant pellets and has a strength lower than that of the hermetic container. A cushioning member presses the partition foil piece toward the gas generant pellets by a resilient force of the cushioning member so as to suppress movement of the gas generant pellets charged in the hermetic container.
