Abstract:
To provide a road surface installation type luminous display board capable of continuing to recognize the content of guide display without impairing the shape and pattern of a guide display portion by side slip and friction even when frictional force (in particular, frictional force in a wear resistant performance evaluation test defined by the Japan Industrial Standard) is applied by pedestrians or vehicles passing through.SOLUTION: There is provided a road surface installation type luminous display board comprising: a bowl-shaped base board which surrounds the surface by a peripheral wall; a plurality of displacement prevention pins which protrude in a region surrounded by the peripheral wall of the base board; a luminous fluorescent block which is in a state of being embedded in a region surrounded by the peripheral wall, has holes for inserting the displacement prevention pins, has a shape for transmitting information to people, and closely contacts with a nonluminous fluorescent block at the rim; and the nonluminous fluorescent block which is not a luminous fluorescent, is in a state of being embedded in a region surrounded by the peripheral wall, has holes for inserting the displacement prevention pins, has a shape for transmitting information to people, and closely contacts with the luminous fluorescent block at the rim.SELECTED DRAWING: Figure 1
