    • PROBLEM TO BE SOLVED: To suppress the generation of noise which deteriorate the guiding accuracy of a flying body by reducing a loading force to a plug by thrust gas and a flow of consumed thrust gas. SOLUTION: A plug 53 is provided with a gas-injection-chamber-side pressure receiving portion 63 and a gas-supply-camber-side pressure receiving portion 65. The pressure receiving portion 63 is arranged so as to freely move between a gas injection chamber 43 and a gas passage 45, and provided with pressure receiving faces 61, 62 producing a loading force F0 in a moving direction C1 from a gas supply chamber 42 to the gas injection chamber 43 by thrust gas pressure. The gas-supply-camber-side pressure receiving portion 65 is arranged so as to freely move between the gas supply chamber 42 and the gas passage 45, and provided with a pressure receiving face 64 producing a loading force F1 in a moving direction C2 from the gas injection chamber 43 to the gas supply chamber 42 by the thrust gas pressure.
