Claims

[Scope of utility model registration request]

The column tube into which the steering shaft is inserted is configured to be able to slide along with the steering shaft in the axial direction relative to the vehicle body side, and between the column tube and the vehicle body side, there is a space between the column tube and the vehicle body side to prevent the forward impact of the vehicle body from being applied to the steering shaft. In an energy-absorbing steering device equipped with a shock absorbing mechanism that absorbs shock with a shock-absorbing member, a column mounting bolt is used to install a support on the side of the column tube on the vehicle body side, and a support is installed on the side of the column tube or A locking hook is planted on the bottom surface,
The shock absorbing member is composed of a linear body having a coil-shaped plastically deformed part and a locking part, and is placed on the side of the column tube, and the plastically deformed part of the shock absorbing member is wound around the support column. An energy absorbing steering device characterized in that a locking portion is locked to the locking hook.
