Collision-energy-absorbing means of an impact-absorbing steering column apparatus includes guide slots 31 a 1 and 31 b 1 , guide slots 31 a 2 and 31 b 2 , and transition portions 31 a 3 and 31 b 3 , as well as energy-absorbing members 36 and 37 , so as to change absorption load for secondary collision energy. A collar 42 plastically deforms the energy-absorbing member 36 or 37 , thereby absorbing secondary collision energy of an occupant in the event of a collision of a vehicle. The guide slots 31 a 1 and 31 b 1 , the guide slots 31 a 2 and 31 b 2 , and the transition portions 31 a 3 and 31 b 3 change an absorption load for secondary collision energy dependently on the direction of a secondary collision of the occupant with the steering system.
