PROBLEM TO BE SOLVED: To improve responsiveness by a small and lightweight driving mechanism in a dynamic wind testing model having a rudder surface driving mechanism. SOLUTION: A ball screw shaft 2 is connected to a servomotor 1, and a moving body 3 threadedly engages with the ball screw shaft 2. The moving body 3 is connected with one end of an arm 13 via a moving body lever 11 and a shaft 12, and the other end of the arm 13 is connected to a rudder surface 20 by a shaft 14 of a rudder surface side lever 15. When the ball screw shaft 2 rotates, the moving body 3 moves, and a link mechanism 10 composed of 11, 12, 13, 14, and 15 moves, and rotates the rudder surface 20 with a shaft 21 as the center, and moves the surface as 20a and 20b. The small and lightweight driving mechanism superior in responsiveness can be incorporated into the wind testing model. COPYRIGHT: (C)2003,JPO
