とした自動車の後輪操舵装置。 A hydraulic cylinder for rear wheel steering, in which the piston rod moves from the neutral position to the left and right steering positions to steer the rear wheels; a return device for the piston rod, which returns the piston rod of the hydraulic cylinder to the neutral position and holds it there; When the steering is performed from the neutral position and the steering angle reaches the first set steering angle, which is smaller than the maximum steering angle, the rear wheels are steered from the neutral position by a predetermined angle via the rear wheel steering hydraulic cylinder, and the front wheels are turned to the neutral position. When the steering wheel is steered in the neutral position direction and the steering angle becomes a second set steering angle smaller than the first set steering angle, the rear wheels are steered toward the neutral position via the rear wheel steering hydraulic cylinder. A rear wheel steering device for an automobile, comprising a control valve that returns and maintains the piston rod to a neutral position via the piston rod return device.
