特徴とする４輪操舵車両の後輪操舵装置。 In a four-wheel steering vehicle that is provided with a rear wheel steering actuator and a rear wheel steering mechanism that steers the rear wheels by the operation of the actuator, the rear wheel steering mechanism includes a stopper that determines a rear wheel steering angle and a rear wheel. A return spring that biases the vehicle to maintain the vehicle in the straight-ahead position is provided, and a manual switch operated by the driver is provided in the vehicle interior, and when the manual switch is operated to the right-hand or left-hand position when the vehicle speed is less than the set vehicle speed. A control unit is provided that operates the actuator to steer the rear wheels to the right or left, and when the vehicle speed is higher than the set vehicle speed or the manual switch is in the neutral position, the rear wheels are driven straight by the return spring. 1. A rear wheel steering device for a four-wheel steering vehicle, characterized in that it is configured to be held in position.
