PURPOSE: A fibrous cellulosic material is provided to be included as a gap material in a propelling body composition used in an in flator stored in a vehicle. CONSTITUTION: An in flator (20) includes an extended propelling body(28), and the propelling body generates a combustion product including inflated gas used to inflate an air bag since the propelling body is burned when it ignites. Herein, porous generation material including a combination system of the propelling body are supplied to regulate the phase change of an oxide such as ammonium nitric acid according to the change of a temperature such as various temperature cycling from less than -30°C to more than 80°C. In addition, when the porous generation material is mixed with other materials, the porosity of the propelling body as a result is in a range of 15% of volume by supplying the porous propelling composition.
