PROBLEM TO BE SOLVED: To provide a mixer nozzle equipped with a thrust force deflecting function capable of; (i) lowering the exhausting speed by mixing the engine exhaust gas with a low-speed outside air efficiently and reducing the jetting noises effectively, (ii) obtaining an appropriate nozzle area when an airplane, etc., is taking off or landing and on a cruise, obtaining the desired reaction force efficiently, and thereby lowering the rate of fuel consumption, and (iii) having a thrust force deflecting function to change the jetting direction of the engine exhaust gas to any desired direction (up and down and to the left and right). SOLUTION: The mixer nozzle is equipped with a plurality of V-shaped frames 12 having a V-section and a convergent flap 14 and a divergent flap 16 slidable between them, whereby a silencing effect and a function to change the outlet area are established.
