Claims

[Claims for Utility Model Registration] The lower end of a column tube upper member is slidably fitted onto the upper end of a column tube blower member fixed to the vehicle body, and has a substantially U-shaped outwardly bent portion. A plurality of energy absorption plates are disposed along the circumferential direction between the column tube blower member and the column tube upper member, and the outwardly bent portion is located within the lower end of the column tube upper member. In a steering column tube for an automobile, the inner end of the energy absorbing plate is fixed to the upper end of the column tube blower member, and the outer end of the energy absorbing plate is fixed to the lower end of the column tube upper member, A steering column tube for an automobile, characterized in that a cylindrical buckling adjustment member is fitted onto the upper end of the column tube blower member while being interposed between the outer and inner pieces of each of the energy absorbing members.
