PROBLEM TO BE SOLVED: To provide a rollover prevention device that properly prevents a vehicle from overturning due to a side wind.SOLUTION: A rollover prevention device 30 comprises an airfoil-shaped part 31 that is provided on a ceiling surface of a railway vehicle 10 and the cross-section of which assumes an airfoil shape. The airfoil-shaped part 31 has an inclination with respect to a side wind adjusted to generate an aerodynamic force in a predetermined direction on the occurrence of the side wind. The aerodynamic force has a component acting toward the occurrence side of the side wind in a vehicle width direction, and a component acting in a vertical downward direction. The airfoil-shaped part 31 assumes a shape formed by dividing an ellipsoid into quarters, and assumes a fan shape having a central angle of 90 degrees in a side view.SELECTED DRAWING: Figure 11

    【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。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と、鉛直下方方向に作用する成分とを有する。翼形部31は、楕円体を1/4分割した形状を有し、且つ側面視において中心角が90度の扇形状を有する。【選択図】図11
