A rack member is connectable with the steerable wheel of the vehicle and has rack teeth formed thereon. The rack member is axially movable relative to the housing. A rotatable pinion gear is in meshing engagement with the rack teeth on the rack member. The rack member is axially movable relative to the housing to turn the steerable wheel of the vehicle in response to rotation of the pinion gear. The pinion gear is rotatably driven by an electric motor to axially move the rack member relative to the housing.</p> |
