<p>PURPOSE:To make the realization of the deadband where a rear wheel is not steered with simple constitution by providing a displacement transfer member transferring the steering displacement of a front wheel to a rear wheel side and a right and left pair of a rotation transfer member forming the deadband. CONSTITUTION:When a steering angle transfer shaft 9 rotates to the A direction by steering a handle, cam plates 13 and 14 rotate in the D and E directions respectively following the rotation mentioned above. But a rear wheel is not steered with a tie rod 26 held at a neutral position regardless of the steering of the handle since locking pins 15 and 16 provided to the tie rod 26 side are abutting the deadband part of each cam plate 13 and 14 until the steering angle of the handle reaches a given angle. When the steering angle of the handle exceeds a set angle, the rear wheel is steered since a cam engaging pin 15 engages with the displacement transfer part of the cam plates.</p> |
