PURPOSE: An impact absorptive steering column of a vehicle is provided to absorb impact by destroying a deformable portion of an inner tube using a protrusion of a collapse bush. CONSTITUTION: An impact absorptive steering column of a vehicle comprises an inner tube(310), a collapse bush(320) and an outer tube. The inner tube has one or more deformable parts(311). The deformable part of the inner tube is depressed to the inside of the upper circumferential surface of the inner tube in an axis direction. The collapse bush is combined on the outer circumference of the upper side terminal of the inner tube. The collapse bush has one or more projections(325). The projection of the collapse bush protrudes from the inner circumference. The outer tube is combined in the outer circumference of the collapse bush. The outer tube moves in the collision of the vehicle with the collapse bush.
