To improve the ease of recognition in an opening direction while preventing the breakage due to snow damage.SOLUTION: A turnout opening direction display device 10 includes a display part 12 having four display plates 14A to 14D connected to a shaft rod 16 in a cross shape, a crank part 20 forming an U-like cutout part 22 extending in a bifurcated shape from a lower end of the shaft rod 16 and held to be rotatable in a range of 90 degrees between a first rotation position and a second rotation position, and a drive mechanism 30 for display having a switch roller 32 in which the switch roller 32 is moved while being loosely fitted to the cutout part 22 during driving of a link mechanism 102 so as to rotate the crank part 20 to the first rotation position or the second rotation position. Since opening direction displays of two tracks are simultaneously displayed on two display plates 14A, 14C or 14B, 14D arranged in right and left, the ease of recognition in the opening direction can be improved. In addition, since a display part 12 is installed outside the gauge, the collision of a snow block and the like against the display plates 14A to 14D can be prevented.SELECTED DRAWING: Figure 2

    【課題】雪害による破損を防止しながら、開通方向の認識し易さを向上する。【解決手段】分岐器開通方向表示器10は、軸棒16に十字状に接続された4枚の表示板14A~14Dを有する表示部12と、軸棒16の下端から二股状に延びてU字状の切り欠き部22を形成し、第1回転位置と第2回転位置との間の90度の範囲で回転可能に保持されたクランク部20と、転換ローラ32を有し、リンク機構102の駆動時に転換ローラ32が切り欠き部22に遊嵌しながら移動して、クランク部20を第1回転位置又は第2回転位置へと回転させる表示用駆動機構30とを含む。これにより、2本の軌道の開通方向表示が、左右に並ぶ2枚の表示板14A、14C又は14B、14Dにより同時に表示されるため、開通方向の認識し易さを向上することができる。又、表示部12が軌間外に設置されるため、雪塊等が表示板14A~14Dへ衝突することを防止できる。【選択図】図2
