To provide a sleeper capable of reducing a roadbed fluidization phenomenon generated at a curved line section of a ballasted track.SOLUTION: There is provided a sleeper installed at a curved line section of a ballasted track in which a width is continuously widely formed toward rail fastening parts 1b, 1c formed at both end parts from a longitudinal center part 1a, and a width of the rail fastening part 1b on the side closer to an outside rail is formed to be wider than a width of the rail fastening part 1c on the side closer to an inside rail.SELECTED DRAWING: Figure 1
【課題】有道床軌道の曲線区間において生じる道床流動現象を抑制することができるまくらぎを提供する。【解決手段】長手方向の中央部１ａから両端部に形成されたレール締結部１ｂ、１ｃに向かって幅が連続的に広く形成された、有道床軌道の曲線区間に設置されるまくらぎにおいて、外軌側のレール締結部１ｂの幅は、内軌側のレール締結部１ｃの幅に比べて広く形成されている。【選択図】図１
