PROBLEM TO BE SOLVED: To provide a trolley wire having small wire curling, and a method for manufacturing the trolley wire.SOLUTION: A trolley wire wound on a drum comprises: a slide contact part which is brought into slide contact with a current collecting device; plural suspension grooves in which a component, which suspends the trolley wire, is fitted; and a step part for wear detection in which widths at prescribed positions between the slide contact part and the suspension grooves are differed. When a straight line connecting the suspension grooves is represented by a straight line α, a perpendicular line, which is orthogonal to a face parallel to a cylindrical surface of the drum and intersects said straight line α, is represented by a perpendicular line β, an intersection angle of the straight line α and the perpendicular line β is 10° or less.SELECTED DRAWING: Figure 1
【課題】線癖が少ないトロリ線及びトロリ線の製造方法を提供する。【解決手段】ドラムに巻回されたトロリ線であって、前記トロリ線は、集電装置に摺接する摺接部と、前記トロリ線を懸架する部材が嵌め込まれる複数の懸架溝と、前記摺接部と前記懸架溝との間の所定の位置の幅を異ならせてなる摩耗検知用の段差部とを備え、前記懸架溝間を繋ぐ直線を直線αとし、前記ドラムの筒表面に平行な面に直交し、前記直線αに交差する垂線を垂線βとするとき、前記直線αと前記垂線βとの交差角度が10°以下であるトロリ線。【選択図】図1
