<p>PROBLEM TO BE SOLVED: To provide a guard rail for a wall face capable of easily and efficiently executing setting working and securing a surely locking state of a covering member after setting working completion without needing delicate setting working by preventing falling-off of the covering member for a skeleton member at the time of setting working. SOLUTION: In a guard rail, a skeleton member 1 has an upward projection edge 3 formed on the upper end of a side wall part 2, a plurality of U-shaped cross section curvatures 4, and a shortage groove 7. A covering member 11 has, a main covering body part 12, a hook-like edge 13 locked on the upward projection edge 3, an arrow cross section projection 14 locked on the shortage groove 7, and a falling-off prevention projection existing within a recess groove 6 in which the uppermost U-shaped cross section curvature 4 is figured.</p> |
