A steering column device includes: a bracket to be fixed to a vehicle body and including a first wall; a steering shaft; a steering column including one end supported by the vehicle body and an outer peripheral surface with a second wall, and configured to rotatably support the steering shaft; and a clamp shaft penetrating the first wall and configured to switch between a pressure and non-pressure contact states respectively where the first and second walls are and are not in pressure contact with each other. The first and second walls include: a pair of first protrusions disposed separately on both sides of the clamp shaft in a first direction parallel to an axial direction of the steering column, and extending in a second direction perpendicular to the axial direction of the steering column; and a pair of second protrusions disposed separately in the second direction and extending in the first direction. Each of the first protrusions contacts both of the second protrusions in the pressure contact state. |
