輌の四輪操舵装置。 A steer valve is provided that is linked to the steering handle, and a steer cylinder that is driven by the operation of the steer valve is connected to the steering wheel. Bell cranks for the front and rear wheels are also connected to the pitman arm of the steer valve via a drag link. In a four-wheel steering system for a vehicle in which the front wheels and the rear wheels are steered by these bell cranks via left and right side rods, the steer valve is connected and interlocked to the front wheel steer valve and the front wheel steer valve via a transmission means. An electromagnetic clutch is interposed between the transmission means and the rear wheel steer valve, and a front wheel neutral sensor and a rear wheel neutral sensor are installed on the front wheel side bell crank and the rear wheel side bell crank, respectively. A four-wheel steering system for a vehicle, comprising: a control device for shutting off the electromagnetic clutch when detecting the neutral positions of the front wheel neutral sensor and the rear wheel neutral sensor based on a high-speed signal from a vehicle speed sensor. .
