Electrically-driven steering column apparatus including: lower jacket; upper jacket axially slidably inserted thereinto; and telescopic drive disposed astride these two jackets. The telescopic drive contains: support member; screw shaft connected to the support member; and electric motor unit fixed to the lower jacket. The screw shaft is rotatably driven by the motor unit to make slidable motion of the upper jacket with respect to the lower jacket thereby allowing telescopic operation. The lower jacket has axially extending evacuation section shaped by partially increasing the inner diameter of the lower jacket, thereby allowing the passage of nut member provided on the upper jacket. Attaching bolt is screwed into the nut member through longitudinally extending rectangular hole defined by the evacuation section. The support member is supported by the upper jacket through the attaching bolt. Pushing member is disposed circumferentially opposite to the evacuation section, for pushing the upper jacket inwardly.
