An electric steering column device includes a column housing, and a first shaft, a connection shaft and a second shaft provided in the column housing. The connection shaft is movable in an axial direction of the first shaft and the second shaft and is connected to the first shaft and the second shaft so as to rotate together with the first shaft and the second shaft. The first and second shaft are connected to the connection shaft so that the first shaft always rotates at the same rotation speed and that a rotation speed of the second shaft is varied depending on whether or not the connection shaft moves in the axial direction. The device is capable of securing an optimized steering performance by adjusting steering responsibility of a steering wheel depending on a driving state of the vehicle.
