Claims

[Scope of Claim for Utility Model Registration] King pin cases are provided at both ends of the front axle, and knuckle arms are installed in each of the king pin cases, and by rotating these knuckle arms, the front wheels are rotated and the aircraft is steered. In the vehicle, an actuator consisting of a double-acting cylinder is installed on the front side of the front axle, approximately parallel to the front axle, and piston rods protruding from both sides of the actuator are connected to each other via a connecting rod. and connected to both the knuckle arms respectively, and on the front axle,
A steering device for a running vehicle, characterized in that a stopper for preventing rotation of the knuckle arm by more than a predetermined amount is provided at a portion with which one side of the knuckle arm comes into contact when the actuator is contracted.
