PROBLEM TO BE SOLVED: To provide an impact absorbing type steering column apparatus capable of adjusting an energy absorption quantity at the time of secondary collision in accordance with the physique of a driver and vehicle speed by changing an operation load absorbing collision energy. SOLUTION: The impact absorbing type steering column apparatus is provided with a collision energy absorbing means for absorbing secondary collision energy of an occupant upon a collision of a vehicle. The impact absorbing type steering column apparatus is further provided with an energy absorption quantity adjusting means for changing a secondary collision energy absorption quantity by the collision energy absorbing means, at least one sensor for detecting a condition of the occupant or the vehicle, and an electric control means for controlling a drive of the energy absorption quantity adjusting means on the basis of a detection result by the sensor.
