Abstract:
PROBLEM TO BE SOLVED: To provide a nonslip structure which has a high nonslip effect and reliability without deficiency due to a through-hole.
SOLUTION: In a nonslip structure 1, a part of steel plate such as a steel plate 2 is shared to form incision lines (a pair of side incision lines 3a, a connecting incision line 3b) for forming a protruded segment, and also a sheared face (edge 7) along the incision line is raised by pulling the protruded segment along the incision lines 3a, 3b up to a height below a thickness of the steel plate 2, and a gap and through-hole on the steel plate are not made by having the sheared face contacted with the steel plate 2.
