<p>PURPOSE:To absorb and shield a backlash between a driving mechanism and a rotary shaft with a pivot by converting the rotating force transferred from the driving mechanism to the rotary shaft into a turning motion with the pivot without directly transferring it to a moving mechanism, then transferring it. CONSTITUTION:When a DC motor 11 is rotatively driven, the rotating force is transferred to a worm wheel 20 engaged with a worm gear, and a rotary shaft 19 is reduction-rotated. A turning shaft 21a is turned eccentrically with the rotary shaft 19. A cam body 23 slide-moves a support rod 15 until the end face of the body 30a of the right ball joint 30 collides with the right stopper section 31 while swaying it via a slide bearing 21b. The maximum steering angle control on one direction of the rear wheel at the time of a low vehicle speed is performed, for example. A backlash between the worm gear and the worm wheel 20 is absorbed and cut off by a pivot 13.</p> |
