1. A sleeve of a steering column, comprising:
two elements including an outer tube and an inner tube mobile in translation relative to one another along a reference axis, and
an adjustment system comprising an adjustment screw for adjustment of an axial position extending along an adjustment axis parallel to the reference axis and constrained to move in translation with a first of the two elements by at least two guide bearings to guide the adjustment screw in rotation about the adjustment axis,
wherein the adjustment screw is inter-engaged with a nut fastened to a second of the two elements so that rotation of the screw about the adjustment axis drives movement of the nut in translation relative to the adjustment screw,
wherein the adjustment screw is driven in rotation by a motor,
wherein at least one of the at least two guide bearings is a first guide bearing with axial force take-up for immobilizing the adjustment screw against movement in translation, and
wherein the motor is offset from said at least two guide bearings and includes a casing supported directly by the adjustment screw.
