Steering device of vehicle

A steering device of a vehicle, the steering device comprising:

• an upper tube receiving a steering shaft;
• a lower tube receiving the upper tube;
• a movable bracket to which one end of the lower tube is hinged;
• a fixed bracket configured to be fixed to a vehicle body, wherein the movable bracket is slidably coupled to the fixed bracket in an axial direction of the steering device;
• a first driver for sliding the upper tube relative to the lower tube;
• a second driver for tilting the lower tube with respect to the movable bracket;
• a coupling bracket coupling the second driver to the fixed bracket;
• and
• a third driver for sliding the movable bracket with respect to the fixed bracket,
• wherein the coupling bracket includes a first coupling part fixed to and immovable with respect to the fixed bracket.
