Abstract
An electric steering column for a motor vehicle is provided, which has a steering shaft. A jacket tube extends along the steering shaft to cover the same. A worm wheel is rotatably held by the jacket tube and has a center bore through which a given portion of the steering shaft loosely passes. A collar member is tightly disposed on the given portion of the steering shaft defining an annular clearance between the collar member and the worm wheel. An elastically deformable structure is put and compressed in the annular clearance in such a manner as to induce a rotation of the collar member when the worm wheel is rotated. An electric motor rotates the worm wheel with an electric power. Due to provision of the elastically deformable structure, a possible ill-alignment between the worm wheel and the collar member is absorbed or compensated.
