PROBLEM TO BE SOLVED: To firmly install a walking guide marker by simple construction and also secure the beauty of a road surface or a floor carpet. SOLUTION: A walking guide marker comprises a projected board 2 which is disposed on the road surface 1 and has a through hole 2a passing through the central part thereof, a hollow rivet 3 formed by increasing the diameter of one end peripheral edge of a cylinder to form a head part 3a and taking the other end part as a shaft part 3b, a wedge 4 with a control rod formed in such a manner that one end part 4b of a control rod 4a freely inserted in the hollow ribet 3 is increased in diameter, and a head plug 5 for closing the through hole 2a of the projected board 2 from the surface side. The projected board 2 has a recessed part 6 inside the peripheral edge of the back thereof. By this arrangement, the projected board 2 can be firmly fixed to the road surface 1 without a tapping screw or the like, and further the recessed part 6 can be used as a paste reservoir, so that an adhesive applied to the back of the projected board 2 can be prevented from leaking out to the outside of the peripheral edge of the projected board 2. |
