るリヤホイールステアリング装置。 A sub-cylinder that is linked to the vehicle's front wheel steering mechanism and generates control hydraulic pressure according to the amount of front wheel steering, and rotatably supports the vehicle's rear wheels by supplying the control hydraulic pressure generated by the sub-cylinder. A rear wheel steering hydraulic cylinder that rotationally drives the rear wheel steering wheel, a lock mechanism that locks the operation of the rear wheel steering hydraulic cylinder in a neutral position, and a lock that releases the lock mechanism using the control hydraulic pressure generated by the sub cylinder. A release means, and a control valve that is linked to the steering mechanism and supplies the control hydraulic pressure generated when the front wheel steering amount exceeds a set value to the lock release means and the rear wheel steering hydraulic cylinder. Rear wheel steering device.
