PROBLEM TO BE SOLVED: To obtain a rail fastening structure which hardly causes the displacement of a cushioning material below rails.SOLUTION: In a rail fastening structure 100 which presses rails R placed on a steel beam 10 via a track pad 30 and a variable pad 40 toward the steel beam 10 by using insulated pressers 60, a low-friction member 80 is interposed between the rails R and the insulated pressers 60, high-friction layers 30a, 40a are laid at lower faces of the track pad 30 and the variable pad 40, the track pad 30 and the variable pad 40 are made to be hardly dragged by the creeping rails R, and the track pad 30 and the variable pad 40 below the rails R are made to be hardly displaced to a longitudinal direction of the rails R.SELECTED DRAWING: Figure 1 |
