<p>PURPOSE:To vary a rear wheel steering angle randomly by coupling an input link interlocked with front wheel steering to the tip of a control level pivoted to the body while coupling an output link extending to a rear wheel steering member to a pin engagable with an arched groove formed in a control lever. CONSTITUTION:In a rear wheel steering angle ratio control mechanism where a tie rod 5 is displaced by rotation a steering shaft through a pinion rack mechanism 12b so as to steer a front wheel 2, an input link 13 is interlocked with the steering to be driven through a bell crank 7 and a rod 9. The rear end of the input link 13 is pivoted to the tip of a control lever 15 pivoted through a shaft 16 to the body while the front end of an output link 18 is coupled to a sliding pin 14 engagable with an arched groove 31 in the control lever 15 the rear end thereof is coupled with a rear wheel steering member 21. A groove 32 is formed in the shaft 16 which is rotated with the sliding pin 14 being contained in the groove 32 so as to lock the sliding pin 14 thus realizing a rear wheel steering canceled state.</p> |
