The latter comprises pusher arranged at rudder root part to be displaced in drive shaft axis by high-pressure gas, and pivot lever. The latter articulates said pusher and rudder turn part. Rudder root part is equipped with two retainers of rudder turn part at its unfolded position which are composed by spring-loaded rods. Pivot lever lower part interacting with pusher is arranged there above and has transverse hole. Balls and spring-loaded retainers are fitted in said hole on both sides. Said retainers are located in mirror plane of rudder root part perpendicular to drive output shaft axis, on both sides thereof. Pusher top part converges to conical top under spring-loaded balls to interact with the latter at pusher displacement.
