PROBLEM TO BE SOLVED: To provide a pantagraph with small air noise and small aerodynamic drag.SOLUTION: A single arm type pantagraph has a collector shoe, an upper frame 3, a lower frame 4, a balancing rod 5, a base frame 6, and a wind shield 8. The wind shield 8 covers the base frame 6, the bottom of the lower frame 4, and the bottom of the balancing rod 5. The upper frame 3 keeps an upper frame cover 31 fixed to cover an intermediate hinge 9 and a part where the balancing rod 5 protrudes above the wind shield 8. The lower frame 4 keeps a lower frame cover 41 fixed to cover the part protruding above the wind shield 8. The wind shield 8 has an opening 81 where the upper frame cover 31 and the lower frame cover 41 are inserted. The upper frame cover 31 is surrounded by the lower frame cover 41 in a U-shape in a plane view. The opening 81 is blocked with the upper frame cover 31 and the lower frame cover 41 regardless of vertical displacements of the collector shoe during power collection. This constitution reduces aerodynamic noise even when the intermediate hinge 9 is located outside the wind shield 8.

    【課題】空気音が小さく、空力抵抗が小さいパンタグラフを提供する。【解決手段】シングルアーム型のパンタグラフは、集電舟と、上枠3及び下枠4と、釣合棒5と、台枠6と、風防8とを有する。風防8は、台枠6と、下枠4の下部と、釣合棒5の下部とを覆う。上枠3は、中間ヒンジ9と、釣合棒5が風防8より上に突出する部分とを覆うための上枠カバー31が固定されている。下枠4は、風防8より上に突出する部分を覆うための下枠カバー41が固定されている。風防8は、上枠カバー31及び下枠カバー41が挿通される開口部81を有する。上枠カバー31は、平面視で、下枠カバー41によってコの字状に囲まれている。開口部81は、集電時における集電舟の上下変位にかかわらず、上枠カバー31及び下枠カバー41によって塞がれる。これにより、中間ヒンジ9が風防8の外にあっても空力音が小さくなる。【選択図】図4
