Both end parts 5a of the sleeper 5 are inserted in an anti-vibration box 11 of the anti- vibration unit 10. Elastic pads 13, 14, and 15 are added and fixed on inside surfaces 11a, 11c, and 11c sides of the anti-vibration box 11 between facing surfaces of the peripheral surface of sleeper 5 and the inner surface of anti- vibration box 11. A side-part elastic pad 15 added to both inside surfaces 1c (front and rear) of the anti-vibration box 11 is fixed from the outside of the anti-vibration box 11 with a bolt 18 and a nut 19.
