1. A steering column, comprising:
a first sleeve;
a second sleeve, the first sleeve being received in the second sleeve in a telescopic way in a longitudinal direction; and
a gap elimination means comprising:
an elastic pretensioning element and a wedge-shaped body, the wedge-shaped body having a first wedge-shaped surface and a second mating surface; and
an intermediate element, the intermediate element having a third wedge-shaped surface which abuts the first wedge-shaped surface and has a shape fitted to the shape of the first wedge-shaped surface, and the pretensioning element applies a pressing force to the wedge-shaped body via the intermediate element such that the second mating surface of the wedge-shaped body abuts an outer peripheral surface of the first sleeve;
wherein the elastic pretensioning element is arranged in a tangential direction of the first sleeve and applies a pressing force to the intermediate element in the tangential direction, and the intermediate element and the wedge-shaped body apply a force to the first sleeve in a radial direction under the action of the pressing force;
wherein the intermediate element is provided with a first mating part and the wedge-shaped body is provided with a second mating part, the intermediate element and the wedge-shaped body being releasably engaged by means of the first mating part and the second mating part, and the first mating part and the second mating part defining a maximum range of movement of the intermediate element and the wedge-shaped body relative to each other;
wherein the first mating part comprises at least one hook protruding towards the intermediate element, and the second mating part is formed as a recess, the hook and the recess forming a releasable engagement.
