PROBLEM TO BE SOLVED: To provide a simple structure capable of stabilizing the contact state of a current collector with respect to a third rail irrespective of spring bending.SOLUTION: A railway vehicle truck is provided with: a truck frame; a pair of spring lower members that are disposed separately from each other in a vehicle longitudinal direction and support the truck frame via a spring; and a collector beam that is connected to the pair of spring lower members in the state of being extended in the vehicle longitudinal direction and to which a current collector of a third-rail type is attached. Each of the pair of spring lower members has: an axle box that stores a bearing for supporting an axle; a connection mechanism that connects a part of the axle box on a truck center side to the truck frame; a cover member that is disposed outside the axle box in a vehicle width direction and is connected to the axle box so as to be rotatable about the axis of the axle relatively to the axle box, and to which the collector beam is connected; and an elastic bush that is interposed between the cover member and the axle box and is disposed concentrically with the axle.SELECTED DRAWING: Figure 1 【課題】バネの撓みにかかわらず第三軌条に対する集電装置の接触状態を安定させる簡素な構造を提供する。【解決手段】鉄道車両用台車は、台車枠と、車両長手方向に離れて配置され、バネを介して前記台車枠を支持する一対のバネ下部材と、車両長手方向に延びた状態で前記一対のバネ下部材に接続され、第三軌条方式の集電装置が取り付けられる集電梁と、を備える。前記一対のバネ下部材の各々は、車軸を支持する軸受を収容する軸箱と、前記軸箱の台車中央側の部分を前記台車枠に連結する連結機構と、前記軸箱の車幅方向外側に配置され、前記軸箱に対して前記車軸の軸線周りに相対回動可能に前記軸箱に接続され、前記集電梁が接続されたカバー部材と、前記カバー部材と前記軸箱との間に介在し、前記車軸と同心状に配置された弾性ブッシュと、を有する。【選択図】図１
