PROBLEM TO BE SOLVED: To easily unify the pressurized fluid to be discharged from a plurality of openings cut along the axial direction of a diffuser by partially placing one of the openings for discharging the pressurized fluid opposite to an injection part. SOLUTION: The discharge quantity of the pressurized fluid to be discharged from openings 2a, 2b, 2c, 2d for discharging the pressurized fluid is approximately uniform, and, in particular, the discharge quantity of the pressurized fluid to be discharged from the openings 2a, 2d for discharging the pressurized fluid which are located closer to each end of an inflator 1 is set to be a stricter uniform value. Because approximately 87% of the area of a discharge part 1c is opposite to the opening 2a for discharging the pressurized fluid, the discharge quantity of the pressurized fluid to be discharged from the openings 2a, 2b, 2c, 2d for discharging the pressurized fluid can be easily unified by determining the discharge quantity of the pressurized fluid to be directly discharged from the opening 2a for discharging the pressurized fluid. |
