PROBLEM TO BE SOLVED: To continue to support a vehicle body by preventing separation between a bogie frame and a wheel shaft, even when a steering device of a steering bogie ruptures.SOLUTION: A steering bogie 11 for rolling stock includes a shaft box supporting device of a steering shaft 2, which performs the vehicle-traveling-direction longitudinal support of each shaft box 4 for rotatably supporting the steering shaft 2, by the steering device 3 in which a steering link 2a rotatably connected to the shaft box 4 and a connection link 3c rotatably connected to a bolster 7 are each rotatably connected to a steering lever 3b rotatably connected to a bogie frame 6. When the forward and backward movement of the shaft box 4 exceeds a forward and backward movement range in maximum steering during passage through a minimum curve, stoppers 12, which is installed in a range where the distance from the maximum range of the forward and backward movement of the shaft box 4 is larger than 0 and smaller than the maximum amount of the forward and backward movement of the shaft box 4 so that the shaft box 4 of the steering shaft 2 abuts, are installed on both the sides of expansion and contraction of a wheelbase in the bogie frame 6. Since an attack angle between a wheel and a rail can be suppressed to be equivalent to an attack angle for a normal bogie even when the steering device ruptures, safety is enhanced.

    【課題】操舵台車の操舵装置が破断しても、台車枠と輪軸の分離を防止して車体を支持し続ける。【解決手段】操舵軸2を回転支持する各軸箱4の車両進行方向の前後支持を、台車枠6に回転自在に連結される操舵てこ3bに対して軸箱4に回転自在に連結される操舵リンク2aとボルスタ7に回転自在に連結される連結リンク3cをそれぞれ回転自在に連結した操舵装置3で行うようにした操舵軸2の軸箱支持装置を備えた鉄道車両用操舵台車11である。軸箱4の前後移動が最小曲線を通過する際の最大操舵時の前後移動範囲を超えたときに、操舵軸2の軸箱4が当接すべく、軸箱4の前後移動の最大範囲からの距離がゼロよりも大きく、軸箱4の最大前後移動量よりも小さい範囲に設置したストッパ12を、台車枠6における軸距が伸びる側と縮まる側の両方に設置する。【効果】操舵装置が破断しても、車輪とレールのアタック角を通常台車並みに抑制できて安全性が高まる。【選択図】図2
