To provide a single arm pantograph 1 in which rigidity of a pair of frame works in a vehicle width direction w having a lower frame 41 and an upper frame 42 is efficiently increased and a hinge part 5 is constituted with a more rigid structure.SOLUTION: A single arm pantograph is configured such that: a second opening 111 is opened in a hinge plate 11 of another end portion 41b of a lower frame 41; a disc spring unit 18 composed of a singular or a plurality of disc springs 181 to be inserted into the second opening 111 in a vehicle width direction w is provided in a hinge part 5; the disc spring unit 18 is brought into contact with a bearing presser 15 internally fitted to a cylindrical part 42e of an upper frame 42 and a lid 13 fixed to the hinge plate 11; the disc spring unit 18 is compressed inward in the vehicle width direction w due to screwing of a female screw member 16 to a male screw 122 constituting a part at a terminal side of a pin 12 projecting outward in the vehicle width direction w from a first opening 131 of the lid 13; and an axial load toward an inner side in the vehicle width direction w acts on a bearing 14 internally fitted to the cylindrical part 42e of the upper frame 42.SELECTED DRAWING: Figure 3

    【課題】下枠41及び上枠42を有する一組の枠組の車幅方向wの剛性アップが効率的に行われ、ヒンジ部5がより堅牢な構造で構築されるシングルアームパンタグラフ1を提供する。【解決手段】下枠41の他端部41bのヒンジ板11に第2開孔111が開設され、第2開孔111に車幅方向wに内挿される単数又は複数の皿ばね181から構成される皿ばねユニット18がヒンジ部5に設けられ、皿ばねユニット18は、上枠42の筒状部42eに内嵌するベアリング押え15と、ヒンジ板11に固定される蓋13とに接触し、蓋13の第1開孔131から車幅方向wの外方に突出するピン12の末端側の部分を構成する雄ねじ122への雌ねじ部材16の螺合によって、皿ばねユニット18は車幅方向wの内方に圧縮され、上枠42の筒状部42eに内嵌するベアリング14に車幅方向wの内方に向かうアキシャル荷重が作用する。【選択図】図3
