ABSTRACT:
An intermediate steering shaft including a polygonal tubular shaft, a polygonal solid shaft telescopically received in the polygonal tubular shaft, a spring which thrusts the solid and tubular shafts in opposite lateral directions to eliminate lash attributable to running clearance between the solid and tubular shafts, and a control operative from outside of the tubular shaft to relieve the lateral thrust of the spring. The solid shaft has an outside longitudinal groove facing an inside longitudinal groove in the tubular shaft and cooperating with the inside longitudinal groove in defining a longitudinal passage between the solid and tubular shafts. The spring is a helical coil spring wedged between the inside and the outside longitudinal grooves. The control includes a lever on the coil spring and a lateral slot in the tubular shaft through which the lever protrudes. Pivoting the lever from a locked position to an unlocked position twists the coil spring to reduce its outside diameter to less than the depth of the longitudinal passage so that the solid shaft can be easily inserted in and longitudinally translated relative to the tubular shaft.
