PROBLEM TO BE SOLVED: To provide an energy absorption steering column capable of easily and surely imparting frictional load to absorb energy applied to a steering shaft.SOLUTION: A first cylindrical member (upper tube 10) has an outside diameter step part 11 in a position at a predetermined distance away from a vehicle rear opening end and a second cylindrical member (lower tube 20) has an inside diameter step part 21 of an inner circumferential surface smaller than the outside diameter of a large diameter part 13 of the first cylindrical member in the vehicle rear opening end part, and into that, the first cylindrical member is press-fitted. A friction member 30 is wound around the small diameter part 12 of the first cylindrical member to have an outside diameter smaller than the large diameter part and after the large diameter part of the first cylindrical member is removed from the inside diameter step part of the second cylindrical member, the outer circumferential surface of the friction member is arranged to be abutted to the inner circumferential surface of the inside diameter step part of the second cylindrical member. |
