According to the embodiment described above, the completed iron lid 3 is manufactured by manufacturing the mark member 8 having the identification mark for indicating the owner or the administrator as an independent component different from the iron lid 3. Since the mark member 8 is attached to the above, even if the identification target such as the owner or the administrator is different, it is possible to use only one type of iron lid product or casting mold, and reduce the type of iron lid. By applying mass production of various types, it becomes possible to reduce the cost of products and facilitate management. Further, the mark member 8 can be easily attached to the iron lid 3 in a locked state without any tool. Since the mark member 8 cannot be detached from the iron lid 3 once attached, it is possible to prevent the mark member 8 from coming off or being lost after the mark member 8 is installed on the road surface.
