PROBLEM TO BE SOLVED: To provide an adapter for an indirect hot-line tool capable of safely implementing hot-line work in a place where a plurality of wiring exist up and down, and a working method using the same.SOLUTION: The adapter for the indirect hot-line tool is provided in an indirect hot-line tool 140 including jaws provided in distal ends of a pair of opening/closing arms 150 which are opened/closed around an opening/closing shaft by operating an operation part, and made closer or separated with opening/closing of the pair of opening/closing arms. The adapter comprises: a pair of proximal regions 10 and 50 including insertion holes into which the jaws are inserted a pair of arm parts 60 and 70 which extends from the proximal regions, opens/closes while being linked with the opening/closing of the pair of opening/closing arms, has distal end sides being substantially perpendicular in a direction in parallel with an opening/closing shaft 151 of the opening/closing arms, and is tilted in a length direction of an operation rod 148 and a pair of clips 90 and 100 provided at distal end sides of the pair of arm parts and being opposite to each other in the state where the arm parts are closed.SELECTED DRAWING: Figure 11COPYRIGHT: (C)2017,JPO&INPIT【課題】架線が上下に複数存在する場所において安全に活線作業を行うことができる間接活線工具のアダプタおよびこれを用いた作業方法を提供する。【解決手段】間接活線工具のアダプタは、操作部の操作により開閉軸周りに開閉する一対の開閉アーム150のそれぞれの先端に設けられ、一対の開閉アームの開閉に伴って接近または離隔するあご部と、を有する間接活線工具140に備えられる。あご部が挿入される挿入孔をそれぞれ有する一対の基部10、50と、各基部から延び、一対の開閉アームの開閉に連動して開閉し、それぞれの先端側が開閉アームの開閉軸151と平行な方向に対して略直角であり、かつ、操作棒148の長手方向に対して傾斜している一対のアーム部60、70と、一対のアーム部の先端側にそれぞれ設けられ、アーム部が閉じた状態において対向する一対の挟み体90、100と、を備えている。【選択図】図11
