GUARD FENCE

PROBLEM TO BE SOLVED: To provide a guard fence having a column which absorbs a collision load caused by vehicle impact to the guard fence, and prevents a base of the guard fence column from being rolled up.SOLUTION: A rear flange 5 has a bent part 52 at the bottom end of a support plate 51 which rises upward in a state opposed to a horizontal beam mounting plate 45 of a front flange 4. A projecting plate 53 inclined downward toward the rear side projects from the bent part 52. Since the lower end of the projecting plate 52 is fixed to the top surface 31 of a base 3, the rear flange 5 is not tilted down at the lower end, that is, the lower end of the projecting plate 53. Since the rear flange 5 is tilted down toward the rear side around the bent part 52 as a fulcrum, force in the direction of rolling up of the front portion of the base 3 is reduced, resulting in suppression of rolling up of the front portion.
