PROBLEM TO BE SOLVED: To provide a carriage for a railway vehicle in which generated aerodynamic sound can be reduced.SOLUTION: A carriage for a railway vehicle comprises: plural axle boxes which rotatably support a pair of wheel shafts, which respectively have wheels on vehicle width direction both sides, by bearings; a deviation prevention tool which is hung on each of the plural axle boxes, contacts a track when the wheel is deviated from the track and regulates movement of the wheel in a vehicle width direction; and a fairing for the deviation prevention tool which covers the deviation prevention tool, guides air flowing toward the deviation prevention tool from a vehicle longitudinal direction outer side to an inner side, and causes to the deviation prevention tool to appear in the case that the fairing contacts the track when the wheel is deviated from the track.SELECTED DRAWING: Figure 1
【課題】 台車で発生する空力音を低減することができる鉄道車両用の台車を提供する。【解決手段】 鉄道車両用の台車は、車幅方向両側に車輪を夫々有する一対の輪軸を軸受によって回転自在に夫々支持する複数の軸箱と、前記複数の軸箱の各々に垂下され、車輪が軌道から脱線した際に軌道に当たって車輪の車幅方向に移動を規制する逸脱防止具と、逸脱防止具を被覆すると共に、前記逸脱防止具に向かって流れる空気を車両長手方向外側から内側へと受け流し、且つ車輪が軌道から脱線した際に軌道に当たると逸脱防止具を表出させる逸脱防止具用フェアリングと、を備えている。【選択図】 図1
