A steering column having a variable impact-absorbing structure includes an inner column tube, an outer column tube disposed at an outer circumferential part of the inner column tube, a guide fixed to an outer circumferential surface of the outer column tube, a strap having a deformable part fitted into the guide, a pin inserted through the strap and configured to be slidable into the guide, a solenoid that drives the pin, and a control unit that controls the solenoid. The steering column further includes a sensor that senses a state of a driver and outputs the sensing result to the control unit, wherein the strap comprises a plurality of parallel wires, one end of each wire being opened and the other end of each wire being connected to each other in a closed state, and a suspending end that is bent in a loop shape is formed on the closed end to enable the inner column tube to be suspended thereon.
