CONSTITUTION: A plurality of sliding prevention bars are arranged on the upper surface of an upper plate, and a reinforcement wall is arranged on the lower surface of the upper plate. A side wall is attached to both sides of the upper plate. A lower plate including a plurality of sliding prevention bars is attached to the lower part of the upper plate. The sliding prevention bar is transformed into a protrusion by a roller press. The roller press includes a forming roller of a toothed wheel shape. [Reference numerals] (S110) Prepare an upper plate formed with sliding prevention bars; (S120) Attach side walls to both sides of the upper plate; (S130) Attach a lower plate to the lower part of the upper plate; (S140) Transform the sliding prevention bars into protrusions
