PURPOSE:To insure safety of crew from high temperature combustion gas flow and facilitate to reinforce an air bag by forming an exhaust port on the circumferential wall part in the vicinity of a flange part in the radial direction. CONSTITUTION:Gas generated in a combustion chamber 5 is passed through an opening 8 and let flow into an air bag 10 through coolant 12, a filter 13, and an exhaust port 9. The exhaust port 9 is provided on the thick circumferential wall part 1c of a diffuser. The position of the exhaust port 9 is in the vicinity of a flange part 1a, and the direction is faced in the radial direction. A distance D is formed between the exhaust port 9 arranged in the vicinity of the flange part 1a and the air bag 10 having the bag port 10a mounted in the vicinity of the flange part 1a. Gas flow 14 is passed through the exhaust port 9, ejected in the radial direction, the air bag 10 is expanded in the radial direction, and then quickly expanded in the axial direction. |
