Abstract
An energy absorbing steering column includes a first cylindrical member for accommodating a steering shaft of a vehicle and a second cylindrical member for accommodating the first cylindrical member and normally supporting the first cylindrical member in a predetermined position to allow the first cylindrical member to axially move relative to the second cylindrical member upon a predetermined or greater load applied to the steering shaft. The first cylindrical member includes first and second enlarged diameter portions, and the second cylindrical member includes first and second supporting portions. An elastic bush is provided between the first enlarged diameter portion and the first supporting portion for applying elastic force for supporting the steering shaft to restrict an axial movement of the first cylindrical member relative to the second cylindrical member.
