To provide a truck for a rail-vehicle which can reduce air resistance while workability to inspect and maintain each part of the truck is not worsened.SOLUTION: A truck for a rail-vehicle comprises a pair of yaw dampers 40 which suppress yawing of a truck 20 and anti-rolling devices 29 which suppress rolling of a railroad vehicle 1 and the yaw damper 40 comprises, in the end side of the rail-vehicle in its width direction (Y direction), a windbreak cover 46 which suppresses turbulence of air stream flowing around the neighborhood of the truck 20 and therefore air flowing along a side cover 12 provided under the rail-vehicle is peeled from the side cover 12 and then flows smoothly along a side face of the yaw damper 40 and the anti-rolling device 29.SELECTED DRAWING: Figure 4

    【課題】台車の各部の保守点検に関わる作業性を損なうことなく、空気抵抗を低減できる軌条車両用台車を提供する。【解決手段】軌条車両用台車は、台車20のヨーイングを抑制する一対のヨーダンパ40と、鉄道車両1のローリングを抑制するアンチローリング装置29と、を備えており、前記ヨーダンパ40は、軌条車両の幅方向(Y方向)の端側に、台車20の近傍を流れる空気の流れの乱れを抑制する風防カバー46を備え、これにより軌条車両の下方に備えられる側カバー12に沿って流れる空気が、側カバー12から剥離した後、ヨーダンパ40の側面と、アンチローリング装置29と、に沿ってスムーズに流れる。【選択図】図4
