<p>PURPOSE:To reduce the driving force required for adjustment of a steering angle and improve the responsibility by providing a drive for moving a slide member at right angles to an output member, and controlling actuation of the driven in response to vehicle speed. CONSTITUTION:A rear wheel steering mechanism 21 is composed of a rotary input shaft 22, a main shaft 24, a slide member 31 and a drive 41, and the input shaft 22 is formed at the rear end thereof with a pinion 23, and the main shaft 24 is provided directly above the pinion 23, and an internal gear 25 is erected at the rear portion of the main shaft 24, and an arm 26 is formed integrally with the rear surface of the gear 25. The output member 27 is rearwardly spaced from the arm 26, and the slide member 31 is provided between a guide 28 and the arm 26. Actuation of the drive 41 causes a center piece 34 to be moved at right angles to the output member 27 and the slide member 31 to be moved at right angles thereto, so that the steering angle ratio of the rear wheel to the front wheel may be controlled in response to vehicle speed.</p> |
