A positioning type steering column device, comprising a steering column (1) having a bulged part (19) formed by a hydraulic pressure bulge forming method, the bulged part (19) further comprising a pair of flat surface parts (20) opposed, back to back, to vertical plate parts for tightening of a body mounting bracket, the pair of flat surface parts (20) further comprising projected parts (21) outward-projectedly formed toward the vertical plate parts opposed thereto, whereby even if a warpage occurs on the flat surface parts (20) by punching out when the bulged part (19) is formed by the hydraulic pressure bulge forming method, a steering column tightening holding force can be prevented from lowering. <IMAGE> |
