本物品は、電線を保護する防護管を挿入又は抜き取るために用いる電線防護管挿入器である。回転力を与えられて防護管の送り動作を行うゴムローラーは、「内部機構を省略したＡ－Ａ’線断面図」及び「内部機構を省略したＢ－Ｂ’線断面図」に示すように、中空構造を有しており、ガイドレールに押し当てられた部分だけが常時変形した状態となっている。This article is a wire protective tube inserter used for inserting or extracting a protective tube that protects electric wires. The rubber roller that feeds the protection tube by applying a rotational force is shown in "A-A' line cross-sectional view with internal mechanism omitted" and "BB' line cross-sectional view with internal mechanism omitted". , has a hollow structure, and only the portion pressed against the guide rail is in a deformed state at all times.
