PROBLEM TO BE SOLVED: To provide a designed iron cover with a sense of beauty, which exerts a higher anti-slip effect than the conventional designed iron plate, and which hardly causes a side slip even if a narrow tire intrudes onto the iron cover. SOLUTION: A recess 1a is provided on the top surface of a main body 1; protrusive patterns 3 and 3' in an arbitrary planar shape are alternately aligned and arranged in a point-like shape on the recess, so as to form a designated pattern A; and the protrusive pattern 3 is similarly aligned and arranged in a point-like shape on the peripheral portion of the recess 1a, so that a ring-shaped anti-slip strip B is provided.
