To realize a practical structure capable of increasing the number of frictional engagement sections between members that are relatively displaced in response to adjustment of a front-rear position of a steering wheel, in a portion of a front end section of an outer column 11b that opposes to an intermediate section of an adjustment bolt 17a, there is formed a slit 33 that is long in the axial direction of this outer column 11b, and in a portion of the intermediate section of the adjustment bolt 17a that opposes to this outer column 11b, there is provided a pressing member 37, this pressing member 37 pressing the outer circumferential surface of the outer column 11b radially inward, with the rotation of the adjustment bolt 17a, and when fixing the front-rear position, with the rotation of the adjustment bolt 17a, a pair of supporting plate sections 23, which constitute a nipping (fixed) bracket 22a, nipping a nipped (movable) bracket 24a, and at the same time, the pressing member 37 bringing the inner circumferential surface of the outer column 11b and the outer circumferential surface of an inner column 12b into frictional engagement. |
