ABSTRACT:
A rotary telescopeable shaft particularly suited for use as an intermediate steering shaft of a motor vehicle including a cylindrical tubular shaft having a flat side, a cylindrical solid shaft slidably telescoped inside of the tubular shaft having a flat side facing the flat side on the tubular shaft and coupling the shafts for unitary rotation, and a unitized resilient insert concealed in a notch in the solid shaft. The notch has a pair of lateral ramps which converge with the flat side of the tubular shaft and a longitudinal ramp which converges with a cylindrical segment of the tubular shaft. The unitized resilient insert consists of a slider on each lateral ramp, a slider on the longitudinal ramp, and a spring wedging the sliders between the lateral ramps and the flat side of the tubular shaft to eliminate runnning clearance perpendicular to the flat side and between the longitudinal ramp and the cylindrical segment of the tubular shaft to eliminate running clearance parallel to the flat side.
