Abstract
A rear-wheel steering system designed to reduce noise to a minimum at a low cost. The rear-wheel steering system includes an electric motor for generating a rotational force, a nut member connected to the electric motor and rotated thereby, and a rod having both ends connected to rear wheels of a vehicle and an external thread portion in mesh with an internal thread portion of the nut member. The rod is axially moved by rotation of the nut member for rear-wheel steering, but is not allowed to rotate. In the system, the internal thread portion is in mesh with the external thread portion such that each axial center is off-center.
