PURPOSE:To effectively lower temperature of generated gas by arranging a refrigerant between gas generating agents and constituting the refrigerant of a metallic material which can be melted by heat accompanying gas generation of the gas generating agents. CONSTITUTION:A refrigerant 12 is arranged between gas generating agents. This refrigerant 12 forms a ring plate shape having a central hole 12a which can be inserted through a housing member 16, arranged between the gas generating agents as it is inserted through the housing member 16 as the gas generating agents and furnished with a large number of through holes 12b to allow gas to pass on its ring part 12c so that fuel gas of the gas generating agents can pass through it. Combustion gas passes through the through holes 12b of the refrigerant 12 and expands inside of a combustion chamber 5. The refrigerant 12 between the gas generating agents is melted by this combustion gas, takes heat away from the combustion gas at the time and the combustion gas lowers its temperature by it. |
