Abstract
Abstract A steering column for a steering wheel assembly for a motor vehicle has an outer tube with a shorter inner tube in contact with the inner periphery of the outer tube to provide a steering column having a longitudinal portion thicker than the rest of the steering column. The inner tube is inserted into the outer tube and that portion of the outer tube which surrounds the inner tube is mechanically reduced in diameter to fit against the inner tube.
