The present teachings relate to a spacer having a body portion and two or more opposing contact surfaces extending from the body portion, forming an angle with the body portion. The spacer may be adapted to engage with a portion of a steering column assembly to reduce or prevent rotation of a column tube during a telescoping adjustment. The teachings also include an adjustable steering column assembly having a column tube with a portion extending therefrom; a steering shaft supported for rotation at least in part by the column tube; a column housing for at least partially supporting the column tube; and the spacer. The spacer may be secured to the column tube to reduce or prevent rotation of the column tube. The teachings further contemplate a method of limiting rotational travel of a column tube during telescoping adjustment using the spacer.

Steering column anti-rotational device

A steering column assembly () including a mounting structure (); a column housing () having a wall opening () and being fixed in position for upward and downward pivotal motion; a tilt screw () having a threaded shank and a gear; a tilt nut () and optionally a bushing surrounding the tilt nut positioned at least partially within and contacting a surface defining wall opening () and having a threaded bore adapted to receive the tilt screw, the contact between the tilt nut and the wall opening such that the load transmitted from the wall opening to the tilt nut is substantially on axis with the threaded bore; a motor () for raising and lowering the column housing by rotating the gear portion and causing the tilt nut to advance toward or away from the gear, causing the column housing to raise or lower, and wherein the longitudinal axis of the threaded shank can pivot fore or aft as the column housing is raised or lowered.
