PROBLEM TO BE SOLVED: To regularly clean a reflection surface and a light emitting surface every day irrespective of the situation of a delineator being installed. SOLUTION: A self-luminous type delineator is composed of a luminous body 3, a cleaning member for the reflection surface and light emitting surface, a motor 10 to rotate the cleaning member, a solar battery 5, an electricity storing body for light emission 19 and one 17 for motor whereby the electromotive force of the solar battery 5 is accumulated, and a day-night judging circuit 22 to judge the day and night on the basis of the electromotive force of the solar battery 5. When the circuit 22 judges that it is at night, the motor 10 is operated by the electric charges accumulated in the electricity storing body 17 for motor, and the cleaning member is rotated to clean the reflection surface and light emitting surface. |
