To constitute a pantagraph for a railway vehicle which comprises a movable framework 2 which mounted on a frame 1 on a railway vehicle roof and a collector head 4 which is elevated by the movable framework, and collects electric power from a trolley wire OI via the collector head, and in which a slider body always contacts the trolley wire over an entire length thereof during the railway vehicle is stopped in a conventional line DC section without damaging such a function as to have good overhead line follow-up.SOLUTION: A collector head has a head body 41 and a slider body 42 which is provided on a top face of the head body 41 and with which a trolley wire is brought into slide-contact in such a manner that a track direction is an X axis and a sleeper direction is a Y axis. The slide body is provided at Y-axis direction both ends of the head body respectively, and is supported by the head body via a universal joint 44 having a rotation degree-of-freedom around the X axis and a rotation degree-of-freedom around the Y axis. The head body is provided with first energization means 91 which energizes the slide body upward at a midship part in the Y axis direction, and second energization means 92 which energizes the slide body around the Y axis so that a top face of the slide body becomes a neutral posture parallel to the X axis.SELECTED DRAWING: Figure 3
【課題】鉄道車両屋根上の台枠1に搭載される可動枠組2と、可動枠組により昇降される集電舟4とを備え、トロリ線Olから集電舟を介して電力を集電する鉄道車両用のパンタグラフを、鉄道車両の走行時、良好な架線追従性を持つという機能を損なうことなく、在来線直流区間での鉄道車両の停車時、すり板体がその幅方向全長に亘ってトロリ線と常時接触するように構成する。【解決手段】軌道方向をX軸、枕木方向をY軸として、集電舟が、舟体41とこの舟体41の上面に設けられてトロリ線が摺接するすり板体42とを有し、すり板体が、舟体のY軸方向両端部に夫々設けられ、X軸回りの回転自由度とY軸回りの回転自由度とを持つ自在継手44を介して舟体に支持される。舟体に、Y軸方向の中央部ですり板体を上方に向けて付勢する第1付勢手段91と、すり板体の上面がX軸と平行な中立姿勢になるようにすり板体をY軸回りに付勢する第2付勢手段92とを設ける。【選択図】図3
