PROBLEM TO BE SOLVED: To properly hold a gap between a tread of a wheel and a brake shoe not only when a wheel shaft is inclined with respect to a truck frame by being steered but also when a journal box is relatively displaced with respect to the truck frame in a steering truck.SOLUTION: A steering truck comprises a truck frame, a wheel shaft, a journal box, a journal box support device, a brake device, and a first pin member. The journal box supports the wheel shaft rotatably and is relatively displaceable with respect to the truck frame. The journal box support device comprises a connection member which connects the journal box and the truck frame, and is supported swingably with an axle center as a rotation center. The first pin member is provided between a connection member and a body frame of the brake device, extends in a vehicle width direction, and transmits the displacement of the connection member to the body frame. The connection member includes a base part, a pivot part which extends from the base part and is swingably connected to the truck frame with the vehicle width direction as an axis line, and a bracket part which projects from the base part and is connected to the first pin member. The axis line of the pivot part of the connection member substantially coincides with the axis line of the first pin member.SELECTED DRAWING: Figure 3

    【課題】操舵台車において、輪軸が操舵されることにより台車枠に対して傾斜した場合に限らず、軸箱が台車枠に対して相対変位した場合においても、車輪の踏面と制輪子との隙間を適切に保持する。【解決手段】操舵台車は台車枠と、輪軸と、軸箱と、軸箱支持装置と、ブレーキ装置と、第1ピン部材とを備える。軸箱は、輪軸を回転自在に支持し、台車枠に対して相対変位可能である。軸箱支持装置は、軸箱と台車枠とを連結し、車軸中心を回転中心として揺動可能に支持される連結部材を有する。第1ピン部材は、連結部材とブレーキ装置の本体フレームとの間に設けられ、車幅方向に延び、連結部材の変位を本体フレームに伝達する。連結部材は、基部と、基部から延びて車幅方向を軸線として台車枠に揺動可能に連結されるピボット部と、基部から突出して第1ピン部材に連結されるブラケット部とを含み、連結部材のピボット部の軸線と、第1ピン部材の軸線とが略一致する。【選択図】図3
