  • the up-and-down motion thereof is carried out freely as the support plate for the rail 2 is lowered downwardly under the guidance of the stay anchor 4 when it is subject to the dynamic load and the support plate for the rail 2 is returned upwardly under the guidance of the stay anchor 4 when the dynamic load transmitted to the support plate for the rail 2 disappears, whereas the front and rear motion as well as the right and left motion, and the unequal subsidence thereof are prevented completely. As a result, there is no possibility of derailment of the train.
  • the device for absorbing the vibration of the rail according to the prior art uses hour small anchor bolts ( ⁇ 26 MM), which are replaced frequently due to corrosion thereof at the damp weather.
  • the device for absorbing the vibration of the rail according to the present invention has an excellent durability since the device for the absorbing the vibration uses two larger anchor bolts ( ⁇ 40 MM).
  • the thickness of the vibration absorbing pad it is possible to maximize the vibration absorbing effect since the support plate for the rail is stabilized in engagement with the stay anchor. In addition, it is possible to improve the durability of the concrete roadbed and the train, and to improve the passenger's feeling of the boarding of the train.
  • the vibration absorbing pad (Fig. 5) comprising the main body and the corner portion which includes a portion of the anchor hole, it is convenient to replace the vibration absorbing pad when it is antiquated or damaged, it is easy to maintain the vibration absorbing pad, and it is possible to reduce the costs including the replacement time for the vibration absorbing pad and the personnel expenses.
