PROBLEM TO BE SOLVED: To relax accuracy in fabrication of an angle and a dimension of an ear piece tip for a trolley wire and an ear tip to contact each other, so as to reduce costs related to the fabrication.SOLUTION: The trolley wire gripper is constituted of: a pressing member 4 that supports and presses from side a trolley wire T which is arranged at a supporting block 1 serving as a base and extends in a horizontal direction (I); and a screw member 7 which is penetrated through the pressing member 4 and screwed to the supporting block 1 so as to press down the pressing member 4 by a head part 8 thereof. The supporting block 1 and the pressing member 4 have ear pieces 2 and 3, whose tip parts are formed in a semi-cylindrical shape, which are line-contacted with a groove part 11 formed on an outer peripheral face 10 of the trolley wire T. By screwing the screw member 7 to the supporting block 1, the tip parts of the ear pieces 2 and 3 are made to grip the groove part 11 of the trolley wire T from a side.SELECTED DRAWING: Figure 1
【課題】トロリ線とイヤー先端が相互に接触するためのイヤー片先端の角度及び寸法の製作精度を緩和して、製作に係るコストを削減する。【解決手段】基台となる支持ブロック1に設置され水平方向(イ)に延びるトロリ線Tを側方から支持する押圧する押圧部材4と、該押圧部材4を貫通して支持ブロック1に対して螺合して押圧部材4を頭部8で押さえ付けるねじ部材7とから構成され、支持ブロック1及び押圧部材4は、先端部が半円筒状に形成されてトロリ線Tの外周面10に形成された溝部11に線接触されるイヤー片2、3を有し、ねじ部材7を支持ブロック1に螺合することにより、該イヤー片2、3の先端部でトロリ線Tの溝部11を側方から把持させることを特徴とする。【選択図】図1
