To provide a rail re-profiling device for easily changing a re-profiling position to a rail surface, reducing a burden when a head part of a rail is re-profiled, and accurately and finely changing the re-profiling position.SOLUTION: A rail re-profiling unit 14 is mounted on a rail running car 11 and re-profiles the rail surface by rotating a milling cutter 14a1. A rail re-profiling position adjustment mechanism 14c swings the rail re-profiling unit 14 in a direction perpendicular to the longitudinal direction of the rail to change the position at which the rail surface is re-profiled, and comprises: a curved guide rail part 14c5 provided with lower curved guide surfaces 14c51, 14c51 guiding lower curved guided surfaces 14a311, 14a311 of a cylinder head 14a3; and a pressing part 14c6 that clamps the cylinder head 14a3 with the curved guide rail part 14c5 and that presses the lower curved guided surfaces 14a311, 14a311 of the cylinder head 14a3 against the lower curved guide surfaces 14c51, 14c51 of the curved guide rail part 14c5.SELECTED DRAWING: Figure 4

    【課題】レール表面に対する削正位置を容易に変更することができ、レールの頭部を削正する際の負担を軽減することができると共に、削正位置を正確かつ細かく変更する。【解決手段】レール走行車11に搭載され、フライスカッター14a1を回転させてレール表面を削正するレール削正ユニット14をレールの長手方向に対し直交する方向に揺動させてレールの表面を削正する位置を変更する削正位置調整機構部14cは、シリンダーヘッド14a3の下側湾曲被ガイド面14a311,14a311を案内する下側湾曲ガイド面14c51,14c51が設けられた湾曲ガイドレール部14c5と、湾曲ガイドレール部14c5との間でシリンダーヘッド14a3を挟み、シリンダーヘッド14a3の下側湾曲被ガイド面14a311,14a311を湾曲ガイドレール部14c5の下側湾曲ガイド面14c51,14c51に押し付ける押付け部14c6とを有する。【選択図】図4
