Steering column device

A steering column device, comprising:

• 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
• disengaging mechanisms provided on a right end portion and a left end portion of 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,
• the first bracket, the second bracket, the disengaging mechanisms, and the like being integrated with one another under a state before the steering column device is assembled onto the vehicle body,
• wherein the first bracket and the second bracket are coupled to each other through an intermediation of a coupling mechanism in a relatively rotatable manner,
• wherein a rotation center of relative rotation, which is performed in the coupling mechanism, is set so as to intersect an axis center of the steering shaft, and
• wherein the coupling mechanism is set so as to allow the first bracket and the second bracket to perform relative rotation when an external force exceeding a predetermined value is applied to the disengaging mechanisms along the column axis direction under a state before the first bracket, the second bracket, the disengaging mechanisms, and the like are assembled onto the vehicle body.
