CONSTITUTION: An electric steering column device comprises a pair of guide brackets(5), a lower mounting bracket(8), an electric motor(9), a power transmission rod(10), and a moving block(6). The pair of guide brackets is installed in an upper tube(3) in parallel in a horizontal direction of a vehicle body. The lower mounting bracket is coupled with a lower tube(4) and fixed in a vehicle body by a hinge(7). The electric motor is fixed in the lower tube. One end of the power transmission rod is connected to the electric motor and the other end is located between the pair of guide brackets for being rotated by the power of the electric motor. The moving block is moved along the guide hole(5a) of the guide bracket. The moving block is thread-combined to the power transmission rod and moved along the guide hole and drives tilt and a telescopic operation.
