PROBLEM TO BE SOLVED: To provide a steering truck which can be configured with a simple structure.SOLUTION: A steering truck comprises: a truck frame supported by a truck body; axles each of which has a wheel shaft and a pair of wheels; bearings each pair of which supports both axial end parts of the axle; axle boxes each of which encases each pair of the bearings; axle box supporting devices each pair of which mounts each pair of the axle boxes onto the hand truck frame; actuators each pair of which is provided to each pair of the bearings, and relatively moves the bearings in a longitudinal direction of the truck body with respect to the hand truck frame, in response to charging/discharging of a fluid; and charge/discharge circuits a pair of which mutually connects the actuators in each pair, and which causes the fluid to communicate between the actuators in each pair to charge/discharge the fluid to/from the actuators in each pair. The charge/discharge circuits are configured to directly charge/discharge the fluid to/from the actuators in each pair conforming to a curvature state of a portion of rails on which the wheels are traveling.SELECTED DRAWING: Figure 6

    【課題】 簡単な構造によって構成することができる操舵台車を提供する。【解決手段】 操舵台車は、車体が支持する台車枠と、車軸及び一対の車輪を有する輪軸と、車軸の軸線方向両側の部分を夫々支持する一対の軸受と、一対の軸受を夫々収容する一対の軸箱と、一対の軸箱を前記台車枠に夫々取り付ける一対の軸箱支持装置と、一対の軸受に対して夫々配置され、流体の給排に応じて軸受を前記台車枠に対して前記車体の長手方向に相対移動させる一対のアクチュエータと、一対のアクチュエータの各々に接続され、一対の軸受の各々が互いに長手方向の異なる方向に相対移動するように一対のアクチュエータの各々に流体を給排する流体給排装置とを備え、流体給排装置は、車輪が走行するレールの曲り具合に応じて前記一対のアクチュエータの各々に対して流体を直接給排するようになっている。【選択図】 図6
