Abstract
A steering apparatus of a steer-by-wire (SBW) system includes a structure for changing the frictional force of the system and a structure for limiting the rotation range of a steering wheel. The steering apparatus includes: a shaft rotatably interlocked with a steering wheel, a friction member surrounding the shaft and contacting the shaft, a frictional force provision device for narrowing and widening the friction member in the radial direction of the shaft to change the frictional force of the friction member that contacts the shaft, and a steering limitation device for regulating the rotation of the shaft using a stopper provided at the friction member during the rotation of the shaft to limit the steering of the steering wheel.
