PROBLEM TO BE SOLVED: To provide a technique for preventing derailing of a railway vehicle without an electric power source.SOLUTION: A vehicle upper side supporter 21 of a truss structure is so provided below a vehicle body outside left and right wheels in a view from the front of a railway vehicle 8 as to fall within a limit. On the other hand, a ground side supporter 22 is so laid along a rail 4 on a top face of a track bed 6 outside left and right rails 4 as to fall within a construction gauge. When a lateral force in a roll direction acts on the railway vehicle 8 and a vehicle body is inclined in a derailing direction, the vehicle upper side supporter 21 collides and contacts with the ground side supporter 22 to support a force in the roll direction, thereby preventing derailing.SELECTED DRAWING: Figure 1

    【課題】無電源で鉄道車両の転覆を防止する技術を提供する。【解決手段】鉄道車両8の車両前方から見て左右車輪の外側の車体下に、トラス構造体の車上側支持体21を車両限界内に納まるように設ける。その一方で、左右のレール4の外側の道床6の上面に、地上側支持体22をレール4に沿って建築限界内に納まるように敷設する。鉄道車両8へ、側方からロール方向への力が作用して車体が転覆方向へ傾斜した際に、車上側支持体21が地上側支持体22に衝突・接触して、ロール方向の力を支え、転覆を防止する。【選択図】図1
