A structure is realized in which the sliding resistance in the axial direction between an inner column and an outer column can easily be contained within an appropriate range. The present invention comprises: the inner column 24; the outer column 25; and a column side bracket 26 fixed by welding to the outer circumferential surface of the outer column 25. The outer column 25 has a front-side small-diameter cylindrical part 37 that is a press-fitted part into which the inner column 24 is press-fitted on the inner-diameter side. The inner circumferential surface of the front-side small-diameter cylindrical part 37 and the outer circumferential surface of the inner column 24 contact in a state having a fastening margin, directly, or via another member, in only a plurality of contact locations separated in the circumferential direction. In the column side bracket 26, at least one location in the axial direction is welded to the outer circumferential surface of the front-side small-diameter cylindrical part 37 in only two weld locations that are close in the circumferential direction.

    实现将内柱与外柱的轴向的滑动阻尼收敛于适当范围中容易的结构。具备内柱(24)、外柱(25)、通过焊接被固定于外柱(25)的外周面的柱侧托架(26)。外柱(25)具有作为将内柱(24)压入内径侧的被压入部的前侧小径筒部(37)。前侧小径筒部(37)的内周面与内柱(24)的外周面在仅在圆周方向上隔离的多个接触位置直接或隔着其他部件具有过盈量的状态下接触。柱侧托架(26)的轴向的至少一个位置相对于前侧小径筒部(37)的外周面仅在沿圆周方向接近的两个焊接位置进行焊接。
