<p>PROBLEM TO BE SOLVED: To provide a rail fastener with a rail fall prevention function, installable on a narrow sleeper.SOLUTION: A rail fastener 100 with a rail fall prevention function comprises a tie plate 10 installed on a sleeper 50 for laying a rail 20, a spring member 3 provided on the tie plate 10 and pressing-down/fastening the rail 20 to the tie plate 10, a first presser plate 1 and a second presser plate 2 superimposably provided on the tie plate 10, and a bolt 4 for fixing the first presser plate 1 and the second presser plate 2 to the sleeper 50 together with the tie plate 10. An inclined plane 10e for guiding a wheel derailed from the rail 20 up to an inclined plate part 2a and a flat surface 10f for installing the spring member 3 are provided side by side on the tie plate 10 in the orthogonal direction to the vehicle advancing direction, so that a device is miniaturized by storing the spring member 3 in a limited space of the tie plate 10.</p> |
