Claims

[Scope of utility model registration request]

An energy-absorbing steering device in which a base of a column tube housing a main shaft having a steering wheel at its tip is supported movably in the axial direction by a clamp bracket, and a tip of the column tube is supported by an energy-absorbing bracket, The energy absorption bracket includes a bracket main body that is fixed to a predetermined position on the vehicle body, and a deformed plate protruding from the bottom of the main body so that it can be bent, and a column tube is attached to the plate surface of the deformable plate. A protruding ring having a press-fitted through hole is provided, and the upper part of the protruding ring is fixed to the upper outer circumferential surface of the column tube, while a secondary collision load acts on the steering wheel, causing the steering wheel and tube to become An energy absorbing steering device characterized in that the lower part of the protruding wheel is set to have a small rigidity so that the lower part of the protruding ring is easily deformed when moving in the direction.
