PURPOSE:To prevent rear wheels from being steered exceeding the predetermined steering angle against the steering of front wheels by providing a device changing in response to the steering angle of the front wheels and limiting the action of a rear wheel steering device. CONSTITUTION:A rectangular frame-like cam member 60 is arranged movably in the longitudinal direction between front wheels 18 and rear wheels 28 by being supported by four pairs of roller 62 and controlled by a front wheel steering device and a front wheel steering angle sensor. The front frame section of the cam member 60 is connected to a rod 66 fixed to a piston rod 14 on the front wheels 18 side via a cable 64. Two congruent and trapezoidal projections are protruded in the left and right directions and are formed point-symmetrically on the inner side surface of the cam member. A rack 90 is arranged movably in the left and rigth directions below the cam member 60, a rack section 92 is formed on one end, and a pin 94 is erected on the other end so that the pin 94 is put in the space of the cam member 60. In addition, a pinion 96 fixed to a rotary shaft 30 is engaged with the rack section 92. |
