Abstract:
1. A steering column device comprising: a bracket including a fixed portion to be fixed to a vehicle body and a first wall extending downward from the fixed portion; a steering shaft having an upper end in an axial direction of the steering shaft for fixing a steering wheel; 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 inside the steering column; a clamp shaft penetrating the first wall, the clamp shaft being configured to switch between a pressure contact state where the first wall and the second wall are in pressure contact with each other and a non-pressure contact state where the first wall and the second wall are not in pressure contact with each other; two first protrusions disposed on one of the first wall or the second wall separately 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, the two first protrusions being disposed with the clamp shaft between the two first protrusions; and two second protrusions disposed on the other one of the first wall or the second wall separately in the second direction and extending in the first direction, wherein each of the two first protrusions contacts both of the two second protrusions in the pressure contact state.
