PURPOSE: To provide a traffic sign for snow removal which is not broken even when a snow removal vehicle or the like is brought into contact with a sign board, or whose visibility is not damaged even when the sign is tilted by the wind pressure. CONSTITUTION: A fixing column is an arm part 1B whose upper side is extended in the transverse direction. A pair of inclined faces 2, 2 for displacement are formed approximately recessed V-shape at the tip surface of the arm part 1B, and a fixing support shaft 3 is projected in the axial direction on the arm part 1B. A supporting cylinder 6 of the sign board to which a longitudinal sign board 13 is fitted is turnably provided on the fixing support shaft 3, and a pair of inclined surfaces 7, 7 for return to slide on a pair of inclined surfaces 2, 2 for displacement are formed approximately projecting V-shape on the supporting cylinder 6 of the sign board. A compressive spring 11 consisting of a coil spring is stretched between the fixing support shaft 3 and the supporting cylinder 6 of the sign board. |
