PROBLEM TO BE SOLVED: To provide an overturn prevention device properly preventing overturn of a vehicle with respect to cross wind.SOLUTION: An overturn prevention device 30 comprises an airfoil part 31 which is provided on a ceiling of a railway vehicle 10 and has an airfoil shape in cross section, and a support part 32 supporting the airfoil part 31. The airfoil part 31 is adjusted in the inclination to cross wind and generates aerodynamic force in a predetermined direction when cross wind occurs. The aerodynamic force has a component acting toward the occurrence side of cross wind in the vehicle width direction. The overturn prevention device 30 is housed inside the vehicle during normal travel and is arranged above the ceiling of the vehicle when cross wind occurs.
【課題】横風に対する車両の転覆を適切に防止する転覆防止装置を提供する。【解決手段】転覆防止装置30は、鉄道車両10の天井面に設けられ、断面形状が翼形状である翼形部31と、翼形部31を支持する支持部32とを備える。翼形部31は、横風に対する傾きが調整されて、当該横風の発生時に所定方向に空気力を発生させる。この空気力は、車両幅方向において横風の発生側に向かって作用する成分を有する。また、転覆防止装置30は、通常走行時には車両内部に収納され、横風の発生時に車両の天井面上方に配設される。【選択図】図2
