<p>PURPOSE: To ensure smooth operation by a method wherein a rear-steering mechanism to move a rear steering shaft through the rotation of a drive shaft in linkage with front when steering comprises a member having a cam groove, and a member provided with a roller engaged with the cam groove, and a bush is arranged at a part of a steering shaft. CONSTITUTION: A rear wheel steering control device is provided with a drive shaft 10 rotated in linkage with front wheel-steering, and a rear-steering shaft 13 is axially moved through a rear-steering mechanism 11 through the rotation of the drive shaft 10. The steering mechanism 11 comprises a member 22 with a cam groove 39 mutually moved in linkage with the drive shaft 10; a member 22 having a cam groove 39; rollers 37 and 38 engaged with the cam groove 39; and a part displacing the rear-steering shaft 13 by a rigid finger piece 36. In this case, the finger piece 36 is arranged integrally with a bush 35 fitted in two end parts adjoining the rear-steering shaft 13. The drive shaft 10 is arranged perpendicular to the axis of the rear-steering shaft 13 and supported such that the rear-steering shaft 13 is movable in parallel to the member 22.</p> |
