Abstract: The present disclosure relates to a steering column, comprising: a first sleeve, a second sleeve and a gap elimination means. The first sleeve is received in the second sleeve in a telescopic way in a longitudinal direction. The gap elimination means includes an elastic pretensioning element and a wedge-shaped body, the wedge-shaped body having a first wedge-shaped surface and a second mating surface. The gap elimination means further comprises 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. The pretensioning element applies a pressing force to the wedge-shaped body via the intermediate element. The steering column according to the present disclosure is capable of stably maintaining a gapless state between the first sleeve and second sleeve, thus preventing noise.
