To provide a trolley wire suppressed in human power and time required for wear management, and enabling wear management even when being unevenly worn.SOLUTION: A trolley wire 1 comprises: linear first grooves 14 along the longitudinal direction, disposed in positions below wear limit positions 20 and above uneven wear limit positions 21 of both lateral faces; and linear second grooves 15 along the longitudinal direction, disposed in positions below the uneven wear limit positions 21 of both lateral faces. The uneven wear limit position 21 is a position in which a cross section in the radial direction when uneven wear having an angle from the horizontal direction of a wear surface as a predetermined ange occurs, and the wear surface in a lower position in both lateral faces reaches the uneven wear limit position 21 is equal to a cross section in the radial direction when being evenly worn to the wear limit position 20.SELECTED DRAWING: Figure 1

    【課題】摩耗管理に必要とされる人手や時間が抑えられ、かつ偏摩耗した場合にも摩耗管理が可能なトロリ線を提供する。【解決手段】本発明の一態様において、両側面の摩耗限度位置20以下かつ偏摩耗限度位置21以上の位置に設けられた、長手方向に沿った線状の第1の溝14と、前記両側面の偏摩耗限度位置21以下の位置に設けられた、長手方向に沿った線状の第2の溝15と、を備え、偏摩耗限度位置21は、摩耗面の水平方向からの角度が所定の角度である偏摩耗が生じて、前記両側面における前記摩耗面の位置の低い方が偏摩耗限度位置21に達したときの径方向の断面積が、摩耗限度位置20まで偏りなく摩耗したときの径方向の断面積と等しくなるような位置である、トロリ線1を提供する。【選択図】図1
