Abstract: A non-slip material exhibiting a high non-slip effect and applicable even to a faulty part where a through hole is made. A part 7 swelling from the upper surface 5a of a steel plate 5 in the direction of plate thickness is provided with a recess 8, and a drain path 9 leading from the recess 8 to the upper surface 5a of the steel plate. Inner circumferential surface of the recess 8 and the groove side surface of the drain path 9 are directed substantially perpendicularly to the upper surface 5a of the steel plate and formed by half blanked shearing planes 8a, 9a where a through hule is not made in the steel plate 5.

Abstract: A non−slip structure capable of increasing a non−slip effect, eliminating a defect caused by a through−hole, and increasing a reliability, characterized in that a part of a sheet metal such as a steel sheet is sheared to form cutting lines for forming projected pieces (a pair of side cutting lines, and a connection cutting line) and the projected pieces are raised along the cutting lines to a larger equal to or higher than the thickness of the steel sheet to raise sheared faces (edges) along the cutting lines so that the sheared faces do not come into contact with the steel sheet to form a clearance and the through−hole in the steel sheet.
