To provide a rail displacement preventing device capable of preventing a longitudinal displacement and being easily manufactured while avoiding fatigue strength deterioration and delayed crack generation of a rail.SOLUTION: The rail displacement preventing device comprises: shear plates 310 fixed to a flat surface on which a base flange 510 of a transverse rail 500 is fixed at required intervals in a longitudinal direction of the transverse rail 500; and a block 530 fastened to the side of a web 520 of the transverse rail 500 so as to be arranged between the shear plates 310 and itself and constrained to move in the longitudinal direction of the transverse rail 500.SELECTED DRAWING: Figure 1
【課題】レールの疲労強度低下並びに遅れ割れ発生を回避しつつ長手方向のずれを防止し得、製造をも容易に行い得るレールずれ止め装置を提供する。【解決手段】横行レール５００のベースフランジ５１０が固定される平面に、横行レール５００の長手方向へ所要間隔をあけて固定されるシャープレート３１０と、シャープレート３１０の間に配設されるよう横行レール５００のウェブ５２０側面に締結され且つ横行レール５００の長手方向への移動が拘束されるブロック５３０とを備える。【選択図】図１
