A guardrail is provided to withstand collision of a vehicle without tearing apart by causing an overlapping part to crush onto a support part. A guardrail comprises a support part(110) and an overlapping part(120). The support part is fixed to posts. The overlapping part protrudes from the support part and has an inner space(122). When the overlapping part is crushed by a vehicle, the overlapping part is overlapped on the support part. The overlapping part shapes into a triangle or a square. |
