A steering system includes a second tooth defining member and an energy absorbing unit. The energy absorbing unit includes energy absorbing portions each including a first portion extending upward in a column axial direction from a restraining portion restrained in the column axial direction and a second portion formed by folding back the energy absorbing portion at a fold-back portion, the energy absorbing portions being separated from each other in a first orthogonal direction, and a coupling portion that couples the second portions together and moves together with the second tooth defining member at the time of the secondary collision. At the time of the secondary collision, the energy absorbing portions allow the fold-back portions to move downward in the column axial direction to absorb impact energy while guiding downward movement of the second tooth defining member in the column axial direction between facing edges of the energy absorbing portions. |
