Claims

[Scope of utility model registration request]

The steering shaft consists of an upper shaft, an intermediate shaft, and a lower shaft connected by a universal joint, and a column tube that rotatably supports the upper shaft is moved approximately axially forward by an impact force toward the front of the vehicle. When an impact force toward the front of the vehicle is applied to a steering wheel that is attached to a part of the vehicle body via a bracket and is fixed to the upper end of the upper shaft, the steering shaft is bent and deformed at the universal joint, and at the same time, In a vehicle impact energy absorbing steering device in which an energy absorbing member attached to the device acts to absorb the impact force, the energy absorbing member is connected to the column tube or a member integral therewith. An impact energy absorbing steering device for a vehicle, characterized in that it is disposed between a vehicle body or a member integral therewith.
