CONSTITUTION: A steering shaft for absorbing impact of a vehicle comprises a tube(3) surrounding upper and lower shafts(1,2); upper and lower columns(4,5) mounted on a circumference of the tube; a tilt bracket supporting the upper column; a circular fixing ring(7) inserted between the lower shaft and the tube; an upper bracket supporting the upper column by being mounted on the tilt bracket; a protrusion unit(7a) penetrating the tube by being attached to an inner circumference of the tube; and a slip formed o the upper bracket of the tilt bracket. Thereby, the steering shaft for absorbing the impact of the vehicle improves safety of a driver by absorbing impact. Moreover, the steering shaft for absorbing the impact of the vehicle improves steering response by removing clearance between the tube and the lower shaft.
