Abstract
A steering column device has a downward U-shaped attachment bracket, an upward U-shaped lower jacket, a polygonal cylindrical mid jacket 3, a polygonal cylindrical upper jacket 4 inserted into the polygonal cylindrical mid jacket 3 and a shock energy absorbing mechanism 26 to absorb a shock energy at the time of a secondary collision. The shock energy absorbing mechanism 26 has a contracting guide part 27 to perform sliding and contracting operation of the upper jacket 4 to the mid jacket 3 separately from an energy absorbing part 28. The contracting guide part 27 is formed by interposing a plurality of linear guides 29 at an overlapping part between the mid jacket 3 and the upper jacket 4, linear guides 29 in which a plurality of bolls 29b arranged in the sliding direction of the mid jacket 3 and the upper jacket 4 are connected to each other through holders 29a.
