<p>PURPOSE: To eliminate steering by a large steering angle at the time of high speed and a small steering angle control, by dividing a motor used at the time of steering by a small steeling angle from that used at the time of steering by a large steering angle, and always regulating the stroke of a rod to which a rear wheel is connected at the time of driving the motor for a small steering angle. CONSTITUTION: At the time of steering by a small steering angle, even when a handle is rotated in any direction right and left, a cam plate 16 is eliminated from turning on switches 17 and 18 to leave both of them in an OFF condition. Consequently, the power source of a first clutch driver 20 is turned ON, that of a second clutch driver 44 is turned OFF, a first electromagnetic clutch 8 become a connected condition, and a motor 12 for a large steering angle is disconnected by a second electromagnetic clutch 43. When the first electromagnetic clutch 8 is in a connected condition, since the stroke of a rod is inhibited from exceeding quantity regulated by a first stroke regulation device 31 even if anything happens, a rear wheel is eliminated from steering by a large steering angle by an error.</p> |
