PROBLEM TO BE SOLVED: To provide a designed iron cover for an underground structure which can largely enhance a design effect compared with that of a conventional product, can attract the higher attention of people than the conventional product, and has an antislip effect.SOLUTION: In the designed iron cover for the underground structure with the antislip effect, an antislip means composed of an uneven structure is provided on the surface of an iron lid body 11, a bordered portion 15 which surrounds a part or the whole of the uneven structure and the upper end surface of which is positioned in a position higher than a top surface of a protrusion 12' constituting the surrounded uneven structure is formed on the surface of the iron cover body, a step 17 flush with the top surface of the protrusion constituting the uneven structure is provided along its inside, and an area enclosed with the bordered portion serves as a design seal application surface 18. The design seal 20 has a thickness which makes a surface of the design seal fixed in a position lower than an upper end of the bordered portion when the design seal 20 is applied and fixed to the top surface and the step of the protrusion, and the surface has the antislip means 21. |
