Abstract
A rear wheel steering apparatus for a vehicle, comprises a hydraulic cylinder for displacing a steering rod connected to left and right rear wheels axially, a centering spring for biasing the steering rod toward a neutral position, and a centering spring cancelling mechanism for preventing a biasing force of the centering spring from acting on the steering rod. A partition wall of the hydraulic cylinder defines an oil chamber in the cylinder and is formed as a cup shape having a central concave portion which constitutes a pressure chamber of the centering spring cancelling mechanism.
