Steering column device

A steering column device comprising:

• an inner column;
• an outer column having a rear-side portion into which a front-side portion of the inner column is internally fitted, a slit extending in an axial direction thereof, a pair of sandwiched portions arranged at positions sandwiching the slit from both sides in a width direction thereof, and a pair of column-side through holes penetrating each of the pair of sandwiched portions in the width direction;
• a vehicle-body-side bracket having a pair of support plate portions sandwiching the pair of sandwiched portions, and a pair of vehicle-body-side through holes provided in portions of the pair of support plate portions that are aligned with each other;
• an adjusting rod inserted through the pair of column-side through holes and the pair of vehicle-body-side through holes;
• a pair of pressing portions arranged on portions of the adjusting rod that protrude from outside surfaces of the pair of support plate portions;
• an expansion/contraction device configured to expand or contract a distance between the pair of pressing portions;
• a telescopic friction plate sandwiched in at least any of a portion between an inside surface of the pair of support plate portions and an outside surface of the pair of sandwiched portions, and a portion between an outside surface of the pair of support plate portions and an inside surface of the pair of pressing portions, and having a telescopic elongated hole through which the adjusting rod is inserted;
• a release bracket arranged inside the slit, and supported by and fixed to the inner column;
• and
• a support bracket having a mounting portion that is joined to the release bracket so as to be able to detach due to an impact load that is applied to the inner column during a secondary collision, and a support arm portion that supports the telescopic friction plate.
