According to the present invention, a plurality of cutting holes spaced apart from each other at predetermined intervals are formed on a guardrail in a longitudinal direction, and a pressing member continuously cuts a bridge surface disposed between adjacent cutting holes and bends the cut bridge surface outward. Accordingly, impact energy is primarily absorbed by an amount equivalent to cutting energy of the bridge surface of the guardrail, and impact energy is secondarily absorbed by an amount equivalent to bending energy of the bridge surface of the guardrail. Therefore, by using the present invention, it is possible to sufficiently absorb the impact energy due to the impact of a vehicle in a process of moving the guardrail by fusing the cutting energy and the bending energy, and the amount of impact energy absorption can be variously adjusted by adjusting the cutting energy and the bending energy.
