ABSTRACT:
A vehicle steering column with means for adjusting the reach of a steering wheel in an axial direction relative to the column includes a coupling between a steering column shaft and a steering column tubular portion, the shaft and tubular portion being relatively slidable. The coupling incorporates a resilient member to provide preloaded torque resistance to inhibit transmission of rotational backlash through the steering column and the shaft and tubular portion are of non-circular section and the resilient member is of non-uniform thickness. In the unstressed state, a sleeve of the resilient member for surrounding the shaft is angularly offset and is twisted into alignment by the non-circular shaft upon assembly of the coupling to provide the torque resistance.
