Claims

[Scope of utility model registration request]

The steering column has a steering column that rotatably supports a steering shaft, a distance bracket fixed to the column, and a column bracket that fixes the column to the vehicle body via the distance bracket, and the steering column supports the steering shaft as an axis. In the steering device, the steering device has an engagement structure that is extendable and retractable in the axial direction and capable of transmitting rotation, the steering column is extendable and retractable in the axial direction, and the angle of the column is adjustable in the vertical direction of the vehicle body. a curling plate provided between the inserted tightening bolt and the column;
a curling plate bending part regulating guide member fixed to the column side and accommodating the curling plate and restraining its U-shaped bending part, and a tightening bolt insertion hole formed in the distance bracket allows the column to expand and contract. The long hole is open to the handle side, and the curling plate has a tightening bolt insertion long hole of the same length as the column expansion and contraction long hole, and the curling plate has a U-shaped bending hole in the event of an impact. An impact-absorbing steering device characterized in that the portion is restrained by the guide member and moves through plastic deformation to absorb impact energy.
