<p>PURPOSE:To improve the stability of control by composing the coupling mechanism of an operation rod for a rear wheel steering device with the first supporting body, the second supporting body and a slider. CONSTITUTION:In steering, the first supporting body 41 in a coupling mechanism A turns about its axis L2. At this time, if the extending direction of a projection 43 slants against the axis L2 of turning by 90 deg., the projection 43 is pushed and moved through the second supporting body 42 and a slider in accompanying with the turning of the first supporting body 41. And an operation rod 21 is pushed and moved in a direction of its axis L1 to steer rear wheels. And if the extending direction of the projection 43 accords with the axis L2 of turning, even if the first supporting body 41 is turned, the first supporting body 41, the second supporting body 42 and the slider are integrally turned only, and the projection 43 is not pushed and moved. Accordingly, the operating rod 21 is not moved and the rear wheels are not steered.</p> |
