とする後輪操向装置。A device comprising a rotatably supported knuckle, a rear wheel attached to the knuckle, and a steering actuator for rotatably driving the knuckle, the steering actuator having a steering cylinder chamber and a rear wheel attached to the knuckle. A piston slidably provided in a lock cylinder chamber, a piston rod connected to the piston, a lock part protruding from the piston rod and housed in the lock cylinder chamber, and a lock part located on both sides of the lock part. a lock body that is slidably provided in a lock cylinder chamber and that clamps the lock portion of the piston rod by hydraulic pressure supplied to the lock cylinder chamber to hold the piston rod in a neutral position;
In addition, when steering, hydraulic pressure is selectively supplied to both sides of the piston to steer the rear wheels, and when in neutral, hydraulic pressure is supplied into the lock cylinder chamber to clamp the lock part with the lock body to maintain neutral position. A control valve mechanism is provided to hold this control valve mechanism. A rear wheel steering device characterized in that a pilot type check valve is provided to maintain the hydraulic pressure supplied to the lock cylinder chamber.
