Claims

[Scope of utility model registration request]

When the steering column is supported by the vehicle body side bracket in a state in which a movable member provided on the steering column is temporarily connected to the vehicle body side bracket, and the steering column is moved by an impact force acting in the direction of its longitudinal axis. Preferably, the shock absorbing steering device absorbs impact force by releasing the temporary connection between the movable member and the vehicle body side bracket, and the steering device is broken at the temporary connection between the movable member and the vehicle body side bracket and detached. A moment due to an impact force transmitted through the movable member acts on the fracture portion in a direction substantially perpendicular to or at an angle of inclination to a plane containing the fracture portion, and the fracture portion is sheared. A shock-absorbing steering device characterized by a shock-absorbing steering device.
