PROBLEM TO BE SOLVED: To provide a pantograph which is excellent in both of stabilization of lifting power and reduction in aerodynamic sound and is equipped with a follow-up mechanism providing high followability, without impairing stable lifting power characteristics and low aerodynamic performance for a "collector head for reducing the aerodynamic sound" mounted on a railway vehicle that travels at a high speed.SOLUTION: A pantograph 1 comprises a collector head 3 mounted on a high-speed railway vehicle and collecting power by sliding with a trolley wire. The pantograph 1 comprises a liftable framework 5 installed on a roof 100 of the vehicle, a core member 31 rigidly installed at its top and extending in the sleeper direction, and a collector head 33 supported by the core member 31 via elastic members 35 and 34. The collector head 33 is divided into a plurality pieces in the sleeper direction, and its cross-sectional shape in a cross section vertical to the sleeper direction is a shell shape wrapping the core member 31.SELECTED DRAWING: Figure 1

    【課題】高速で走行する鉄道車両に搭載される「空力音低減を図った舟体」に対して、安定な揚力特性と低空力音性能を損なうことなく、高い追随性能が得られる追随機構を装備した、揚力安定化と空力音低減の双方に優れたパンタグラフを提供する。【解決手段】パンタグラフ1は、高速鉄道車両に搭載され、トロリ線と摺動して集電する舟体3を有する。パンタグラフ1は、車両の屋根100上に設置され、昇降可能な枠組5と、その頂部に剛に取り付けられた、まくらぎ方向に延びる芯部材31と、該芯部材31に、弾性部材35、34を介して支持された舟体33と、を備える。舟体33は、まくらぎ方向に複数に分割されているとともに、そのまくらぎ方向垂直断面における断面形状が、芯部材31を包む殻状である。【選択図】図1
