舵規制装置。The rear wheel steering link mechanism is operated by a double-acting cedar hydraulic cylinder that is controlled according to the steering state of the front wheels and whose piston is located approximately at the center of the cylinder main body in the straight-ahead state, and the rear wheels are linked to the steering operation of the front wheels. In a front and rear wheel steered vehicle, a floating piston is disposed on both sides of the piston in the cylinder body so as to be able to slide in the axial direction and in a fluid-tight manner, and the floating piston and the cylinder body form a pair of floating pistons. A sub-oil chamber is formed, and both of these sub-oil chambers are connected to a hydraulic power source via a first on-off valve. Ports that open into the main oil chambers formed on both sides of the piston are formed in the center of the cylinder body, and both ports are connected to a reservoir tank via a second on-off valve to connect the rear wheel steering. The control device opens both of the on-off valves when the steering angle of the rear wheels is not appropriately linked to the steering operation of the front wheels, and closes both of the on-off valves when the rear wheel steering angle is appropriately linked to the steering operation of the front wheels. A rear wheel steering control device that controls the operation of the on-off valve.
