To provide a fixing device for a steering device capable of tilt adjustment and having a very simple cam structure. The fixing device includes a fixed bracket; a movable bracket; a lock bolt that passes through the fixed bracket and the movable bracket; a main drive cam, through which the lock bolt passes, and that is fitted to rotate freely; and a driven cam, through which the lock bolt passes, and that is fitted unrotatably. Cam operation parts are formed on the main drive cam and the driven cam respectively. Cam operation parts on both sides are always in contact with the other side while the main drive cam and the driven cam separate and come close in the axial direction, and the diameter of the driven cam is larger than the diameter of the main drive cam. |
