Abstract
According to the present embodiments, a torque applied to a torsion bar is attenuated to thus relatively increase the rigidity of the torsion bar, thereby improving the response performance to a driver's steering wheel operation, increasing a responsive torque range, securing the durability of components such as the torsion bar, and simplifying adjustment of the moving distance of a rack bar compared to the number of revolutions of the steering wheel.
