To provide a truck cover which prevents a damage affecting a railway vehicle operation, depending on realization of the fact that the cover is light-weight and highly rigid.SOLUTION: A truck cover in this invention has a structure in which a base material 12 composed of a processed, such as thermally formed, plate substrate 14 made from non woven fabric has a coat 20 sprayed with polyurea resin. Thereby, as fried materials flipped-up by travel winds that a railway vehicle raises collides with the truck cover surface made from polyurea resin, so the collision energy is effectively absorbed and dispersed by the polyurea resin and damages of the truck cover that may affect an operation of the railway vehicle is prevented by the strength of non woven fabric and polyurea resin. Moreover, as both the base material 12 composed of non woven fabric substrate 14 and the coat 20 of polyurea resin are light-weight, so they contribute the attainment of high speeds of the railway vehicle.SELECTED DRAWING: Figure 4

    【課題】軽量かつ高剛性な台車用カバーを実現し、鉄道車両の運行に影響を与えるような台車用カバーの破損を防止する。【解決手段】本発明の台車用カバーは、熱成形等で加工された板状の不織布製基材14で構成される母材12に、吹き付け等によりポリウレア樹脂の被膜20が設けられた構造を有している。これにより、鉄道車両の走行風等によって跳ね上げられた飛来物は、台車用カバーのポリウレア樹脂が設けられた面に衝突するため、衝突エネルギーをポリウレア樹脂によって効果的に吸収・分散しつつ、不織布及びポリウレア樹脂が有する強度によって、鉄道車両の運行に影響を与えるような台車用カバーの破損を防止することができる。更に、不織布製基材14で構成される母材12と、ポリウレア樹脂の被膜20との双方が軽量であるため、鉄道車両の高速化にも寄与することができる。【選択図】図4
