ABSTRACT:
A locking mechanism for a steering column shaft in a steering column housing of a vehicle, includes a smooth bore hollow cylindrical sleeve member overlying a smooth surface steering column shaft. A longitudinal locking slot in an outer surface of the cylindrical sleeve member is engagable with a locking pin member operated by an ignition switch on the steering column housing. Torque transmitted from the steering column shaft to the sleeve member is limited by a bushing member interposed between the steering column shaft and the sleeve member. The sleeve member is supported in the inner race of a steering column bearing mounted in the housing.
