Claims

[Scope of utility model registration request]

The steering device includes a column tube supported by a column bracket on the vehicle body side, and a steering shaft for transmitting the rotation of the steering wheel to the steering wheel rotatably installed inside the column tube, and furthermore, The above column bracket is approximately U
A first deformable bracket formed in a letter shape and having both left and right ends fixed to the vehicle body side, and a first deformable bracket formed in a substantially S shape having an opening in the center into which a column tube can be inserted and whose lower part is a first deformable bracket. and a second deformable bracket which is fixed to the lower surface of the column tube and whose upper part is fixed to the upper side of the column tube.
