PROBLEM TO BE SOLVED: To provide a rear wheel independent steering device capable of smoothly feeding out a female screw member by a male screw member when turning the male screw member by a motor. SOLUTION: The rear wheel independent steering device 10 controls the steering angle of a rear wheel 18 by rotating a motor 38 provided in a housing 30 of an actuator 15, transmitting the rotation of the motor 38 to a male screw member 107, and feeding out an output rod 34 in the axial direction integrally with the female screw member 108 by the turn of the male screw member 107 to expand/contract the actuator 15. The rear wheel independent steering device 10 has a plurality of spherical bodies between a second housing 33 and the output rod 34, and has a rotation preventive unit 35 capable of preventing the rotation of the output rod 34 and supporting the output rod in a feedable manner.
