Abstract
A rear wheel steering device in a four-wheel-steerable vehicle includes a rod member having opposite ends coupled to tie rods for turning rear wheels, an electric motor, and a screw mechanism for converting rotation of the electric motor to axial motion of the rod member. The stator and rotor of the electric motor are disposed coaxially with the rod member, the motor and the screw mechanism being juxtaposed with respect to each other in the axial direction of the rod member. The screw mechanism comprises a threaded portion on the rod member and a nut engaging the threaded portion, the nut being axially pre-loaded.
