PROBLEM TO BE SOLVED: To provide a tilting/telescopic steering device based on a lock mechanism using a pair of pieces and slopes without causing the manufacturing cost to steeply rise. SOLUTION: The tilting/telescopic steering device is structured so that the pieces 11a and 11b move inward when a fastening bolt 14 is driven in the axial direction for fastening through an operating lever 15. The pieces 11a and 11b have slopes 13a and 13b approaching in such a way as crimbing along a pair of slopes 9a and 9b of a guide member 10 having approximately an angle shape, and as a result, move upward toward two columns 1 and 2, which causes a pair of contacting surfaces 12a and 12b to be put in pressure contact with the inner column 1 to generate fastening. The pieces 11a and 11b thrust between the inner column 1 and the slopes 9a and 9b of the guide member 10 and can not approach any more to each other, and the mating side walls 8a and 8b of a bracket 4 are put in pressure contact with the outer side faces of the pieces 11a and 11b, respectively. |
