Provided is a steering column device, including: a first bracket for supporting a column tube that supports a steering shaft in a freely rotatable manner; a second bracket coupled to the first bracket and assembled onto a vehicle body so as to fix the column tube onto the vehicle body; and a disengaging mechanism provided on the second bracket and configured to allow the column tube to be disengaged from the vehicle body forward along a column axis direction under a set load when a secondary impact is caused in the event of collision of a vehicle. In the steering column device, the first bracket, the second bracket, the disengaging mechanism, and the like are integrated with one another under a state before the steering column device is assembled onto the vehicle body. The first bracket and the second bracket are coupled to each other through an intermediation of a coupling mechanism in a relatively rotatable manner, and a rotation center of relative rotation intersects an axis center of the steering shaft. The coupling mechanism allows the first bracket and the second bracket to perform relative rotation when an external force exceeding a predetermined value is applied to the disengaging mechanism along the column axis direction under a state before the first bracket, the second bracket, the disengaging mechanism, and the like are assembled onto the vehicle body. |
