A method of operating a steering apparatus, which includes a cam unit coupled to an outer side of one plate bracket of a pair of plate brackets and configured to apply a pressure inward and an adjusting unit coupled to an outer surface of the cam unit to adjust rotation of the cam unit, and the adjusting unit includes a first spring installed outside the cam unit and a plunger installed outside the first spring, the method comprising:

pressing the plunger inward by a push button provided on an end of the plunger and moving the plunger inward through a stopper, wherein a guide member is fixed to an outer side of the stopper;
moving a guide pin formed to protrude from an outer circumferential surface of the plunger along a guide groove formed in the guide member from an outer side to an inner side of a diagonal groove formed in a diagonal direction;
rotating the plunger to rotate the cam unit so as to press the pair of plate brackets inward;
pressing the plunger inward by the push button provided on the end and then moving the plunger outward by receiving an elastic force of the first spring;
moving the guide pin along the guide groove from the inside to the outside of the diagonal groove formed in the diagonal direction;
and
rotating the plunger to rotate the cam unit to release a pressure of the pair of plate brackets pressed inward.
