PROBLEM TO BE SOLVED: To realize a structure of a steering column device which reduces a force required for extending and contracting a portion which holds an inner column at the inner side in a fitting manner to a small level and thereby improves the operability when a position of a steering wheel is adjusted.SOLUTION: A slit 19a provided on a lower surface of a front part of an outer column 11a comprises: a main slit part 36 extending in an axial direction; and a sub slit part 37 which is formed at a front end part of the main slit part 36 in a circumferential direction, the sub slit part 37 in which the front end part of the main slit part 36 opens at a rear side edge. A circumferential length of one circumferential end part of both circumferential end parts of the sub slit part 37 from the main slit part 36 is longer than a circumferential length of the other circumferential end part from the main slit part 36. Thus, the rigidity with respect to a width direction is lower in one width direction half part of the outer column 11a in which one sandwiched part 20a exists than in the other width direction half part in which the other sandwiched part 20b exists.

    【課題】インナコラムを内嵌保持する部分を拡縮するために要する力を小さく抑えて、ステアリングホイールの位置調節を行う際の操作性を向上させることができるステアリングコラム装置の構造を実現する。【解決手段】アウタコラム11aの前部下面に設けられるスリット19aは、軸方向に伸長する主スリット部36と、主スリット部36の前端部に周方向に形成され、その後側縁に主スリット部36の前端部が開口する、副スリット部37とから構成される。副スリット部37の周方向両端部のうち、周方向一端部の主スリット部36からの周方向長さは、周方向他端部の主スリット部36からの周方向長さよりも長くなっているため、アウタコラム11aのうち、一方の被挟持部20aが存在する幅方向片半部の幅方向に関する剛性が、他方の被挟持部20bが存在する幅方向他半部の幅方向に関する剛性よりも低くなっている。【選択図】図2
