A steering column device where an inner column can be reliably clamped and sufficient rigidity and strength of an outer column can be achieved. A semi-circular arc rib () is formed on the peripheral edge of a closed end section () of a slit (). The rib () is substantially semi-circular are-shaped and projects outward from an outer peripheral surface (A) of an outer column (). Further, linear ribs (A,B) extend linearly toward the vehicle body front side so as to be continuous from the vehicle body front side of the semi-circular arc rib (). The semi-circular arc rib () and the linear ribs (A,B) reinforce the peripheral edge of the slit () of the outer column () whose rigidity and strength are impaired. Thus the rigidity and strength of the outer column () are improved.

Steering column device

An impact absorbing type steering column apparatus provided with a collision energy absorbing device for absorbing an energy of a secondary collision of an occupant upon a collision of a vehicle comprises an energy absorption quantity adjusting device for changing a secondary collision energy absorption quantity of the collision energy absorbing device, at least one sensor for detecting a condition of the occupant or the vehicle, and electric control device for controlling a drive of the energy absorption quantity adjusting device on the basis of a result of detection by the sensor.

Impact absorbing type steering column apparatus

A shock absorbing type steering column apparatus including a collision energy absorbing mechanism for absorbing a secondary collision energy of an occupant upon a collision of a vehicle, comprises an energy absorption quantity adjusting device for changing an absorption quantity of the secondary collision energy absorbed by the collision energy absorbing mechanism, at least one of operation state detecting sensors for detecting a state of the occupant or of the vehicle, a collision detecting sensor for detecting the collision of the vehicle, and an electric control device for controlling a drive of the energy absorption quantity adjusting device on the basis of a result of the detection by the operation state detecting sensor at the point of time when the collision detecting sensor detects the collision of the vehicle.
