Abstract
An energy absorbing steering column includes a first cylindrical member for rotatably supporting a steering shaft of a vehicle, the first cylindrical member including a first press-fit portion formed on an outer surface thereof, a second cylindrical member for normally supporting the first cylindrical member at a predetermined position, the second cylindrical member including a first supporting portion formed on an inner surface thereof, and a metallic elastic bush provided between the first press-fit portion and the first supporting portion for applying elastic force in a radial direction to restrict an axial movement of the first cylindrical member relative to the second cylindrical member. The metallic elastic bush allows the axial movement of the first cylindrical member relative to the second cylindrical member when a load applied to the steering shaft is equal to or larger than a predetermined value.
