Such a shock absorber 10 is well known in the art and will not be described in detail, but as shown in FIGS. 2 and 3, it includes a pair of upper and lower frames 11 and 12 parallel to the front-rear direction. A shock absorber frame 13 is composed of the pair of upper and lower frames 11 and 12. A shock absorber receiver 14 is provided behind the shock absorber frame 13, and a plurality of intermediate pads and upper and lower end pads are alternately stacked in multiple stages between the shock absorber receiver 14 and the companion plate 17. First and second rubber shock absorber 2
1, 22 are provided in a loaded state. In addition, Mamoru Ban is not shown. The shock absorber 10 configured as described above is attached in association with a coupler that connects front and rear vehicles. That is, the connecting portion 18 on the front side of the shock absorber frame 13 is connected to the connecting device, and the lower frame support 19 supporting the shock absorber support 14 is fixed to the vehicle behind by a bracket, for example. Therefore, the impact generated between the front and rear vehicles when the vehicle is connected or accelerated or decelerated is reduced by the compression of one of the rubber shock absorbers 21 and 22.

By the way, the front and rear impacts between vehicles are the first and second.
The rubber shock absorbers 21 and 22 are used for relaxation, but the shock absorber 21 is compressed when the vehicle is pulled, that is, when the space between the vehicles is widened, and is also compressed when the space between the vehicles is narrowed. Since the bridge 14 is fixed to the guard plate of the vehicle, when the rubber shock absorbers 21 and 22 are thus compressed, the shock absorber frame 13 moves back and forth. This movement or the uncomfortable impact generated between the vehicles due to the expansion and contraction of the rubber shock absorbers 21 and 22 is mitigated, and the riding comfort is improved. Therefore, in order to support the front and rear movement of the shock absorber frame 13, the abrasion-resistant resin-made pick-up plate 23 and the pick-up plate support 24 fixed to the pick-up plate 23 are attached to the lower frame support 19 by the support members 2
It is attached with a plurality of bolts / nuts 26, 26, ... Therefore, the pick-up plate 23 smoothes sliding with the lower frame 12, which is a friction member, and suppresses occurrence of wear and abnormal noise caused by friction.

As described above, since the conventional picking plate slides on the friction member, there is a drawback that abnormal noise is generated when the shock absorber frame and the picking plate slide. In other words, since the picking plate slides against the friction member to suppress vibration, frictional vibration cannot be avoided when damping, but the conventional picking plate has no special measures against this frictional vibration. , The frictional vibration leaks to the outside and makes an unpleasant noise. However, the conventional picking plate is also supported by the picking plate receiver. However, since this conventional picking plate support is formed of a normal steel plate such as SS400, which is a strength member that supports the picking plate, it cannot absorb frictional vibrations and leaks to the outside, causing an unpleasant noise. Is the actual situation. Therefore, an object of the present invention is to provide a vibration damping material for railway vehicles with less noise during vibration damping.
