PROBLEM TO BE SOLVED: To provide a road surface passing regulating marker block allowed to be simply connected, stored, kept, carried, disposed and collected, and capable of clearly forming a regulated zone. SOLUTION: This road surface passing regulating marker block 1 is disposed on a road surface of a no-admittance boundary to regulate passing. The block is formed like a tunnel having a designated length and a section narrower at the upper part than at an opening of the bottom, and one end opening 2 and the other end opening 3 are different in size. The upper part or both side lower parts in the vicinity of one end opening are provided with a fitting hole 14, and the upper part or both side lower parts in the vicinity of the other end opening are provided with a projection 12 fitted to the fitting hole 14. The blocks are connected by fitting of the fitting hole 15 to the projection 12. By this arrangement, the blocks can be stacked in multi-layer, stored, carried, and easily connected to each other by making the best use of the difference in size of the end openings. Thus, storage space can be saved, and the continuous passing regulation zone can be simply set. |
