A steering column damper for a power-driven vehicle comprises a jacket tube with a central longitudinal axis; a sliding tube displaceably guided in the jacket tube; a steering shaft, which is mounted for pivotability about the central longitudinal axis relative to the sliding tube and/or the jacket tube and guided through the jacket tube and the sliding tube; at least one working area, which is disposed between the jacket tube and the sliding tube and filled with a damping medium; at least one working-area-volume reduction unit, which is connected with the sliding tube, reducing the volume of the at least one working area upon insertion of the sliding tube into the jacket tube; at least one aperture which opens the at least one working area to ambience for discharge of the damping medium from the respective working area; a closing element for blocking the at least one aperture; and a triggering unit for controllable release of the respective closing element.
