Abstract:
1. An electric telescopic steering apparatus comprising: a jacket including a lower jacket and an upper jacket configured to slide relative to the lower jacket in an axial direction of the lower jacket so as to telescope the jacket; a screw shaft arranged along a longitudinal direction of the jacket and configured to be held under a state where a rotation of the screw shaft is locked by the jacket, wherein the screw shaft includes one end portion supported by one of the lower jacket and the upper jacket; a nut screwed on another end portion of the screw shaft and supported by another of the lower jacket and the upper jacket; a driving section configured to drive a rotation of the nut; and a displacement absorbing section provided between the one end portion of the screw shaft and the jacket, wherein the displacement absorbing section is configured to permit the one end portion of the screw shaft to be displaced on an X-Y plane defined by an imaginary X-axis and an imaginary Y-axis which are substantially perpendicular to an axis of the screw shaft, wherein the displacement absorbing section is configured to permit an angle of the axis of the screw shaft to vary about the X-axis and the Y-axis, wherein the displacement absorbing section includes:
