Abstract
A collapsible steering column includes a bellows tube with a corrugated portion in which the radius varies regularly along the length of the tube. A connective portion is located at both ends of the bellows tube, and transfer portions are located between each of the connective portions and the corrugated portion. By inserting a reinforcement into the end portion of the bellows tube, the strength and rigidity of the connective portion increases. Press forming, stamp forming, rivet forming, and/or adhesive methods are applied to connect the end portion of the bellows tube and the reinforcement.
