Claims

[Scope of utility model registration request]

In an energy absorbing member for a steering device that absorbs a load acting in the axial direction of the steering device by shrinking and deforming a cylindrical member formed in a bellows shape in the axial direction, one side of the winter mountain forming the bellows is made into a cylinder. The shape is perpendicular to the axis of the cylindrical member, or the shape is inclined in the same direction as the other side. An energy absorbing member for a steering device characterized by:
