[Prior art]
In a railway station premises, items such as baggage often fall on the paving stones from the gap between the platform and the railway vehicle. In particular, when the platform is curved according to the curve of the track, a large gap is generated between the platform and the railway vehicle, so that the baggage or the like is likely to fall when getting on and off the railway vehicle.
[0003]
In order to prevent this, a configuration has been conventionally proposed in which a flat gap filler made of wood or metal material is attached to the upper end of the wall surface of the platform to reduce the gap between the platform and the railway vehicle. ing. However, when a gap filler made of wood is attached, there is a risk that the railway vehicle will be damaged or deformed in the unlikely event that the railway vehicle comes into contact. In some cases, the wood may burn with a flame. When a gap filling material made of a metal material is attached, passengers get on and off easily when getting on and off, and when the railway vehicle comes into contact, the railway vehicle is damaged more than wood.
[0004]
In order to cope with such a problem, a platform mounting material having a structure as disclosed in, for example, Japanese Patent Laid-Open Nos. 5-287710 and 6-293256 has been proposed. In the conventional configurations of these publications, the base portion and the comb teeth projecting on one side surface of the base portion are formed of a rubber-like elastic body. Then, in a state where the base portion is attached to the upper end of the wall surface of the platform, the comb teeth are projected to the track side so that the gap between the platform and the railway vehicle is narrowed.

In this conventional platform mounting material, it becomes difficult to slip when getting on and off, and there is almost no risk of damaging the railway vehicle. However, what fills the gap between the platform and the railway vehicle is a comb-like body made of a rubber-like elastic body, so when a load is applied to the comb-teeth body when getting on and off, the comb-teeth body is deformed downward. There is a problem that it is easy and lacks stability. In addition, there is a risk that inconveniences such as a high-heeled heel or the tip of an umbrella being caught in the gap between the comb teeth occur frequently. Furthermore, since the comb teeth have a complicated shape, the manufacturing cost is high. Moreover, the width of the gap between the platform and the railway vehicle varies, but in such a case, it is necessary to prepare a plurality of types of comb teeth bodies having different thicknesses, which is not only complicated, Further cost burden was imposed.
