PROBLEM TO BE SOLVED: To operate an operation lever by a small force and to prevent the operation lever from deviating during the position adjustment of a steering wheel, in a steering column device. SOLUTION: In an urging direction reversal mechanism 8, when centers of an engagement pin 471, a central shaft 81 and an engagement pin 821 are aligned on a linear line in the course of the unclamping of a tilt head clamp 41 and a column clamp 21, since a direction urging the operation lever 7 by an urging spring 715 is reversed from a clockwise direction (white coating arrow Fb) to a counter-clockwise direction (white coating arrow Fc), the urging force of the urging spring 715 is applied as a force for pressing a pusher rod 77 against the urging force of the urging spring 741 and the operation force of a driver required for pulling the operation lever 7 to a steering wheel 92 can be almost a zero. Since an engagement projection 871 is engaged with an unclamp side engagement groove 882, the position of the operation lever 7 is exactly retained to the unclamp side operation end b.
