A spinning reel for fishing includes a rotor, a fishing line guiding mechanism, and a bail reversing mechanism. The rotor has a cylindrical portion, and first and second rotor arms disposed in opposed positions on the cylindrical portion. The fishing line guiding mechanism has a line roller to guide a fishing line, a bail, first and second bail support members supporting first and second ends of the bail, the first bail support member coupled to the first rotor arm, and the second bail support member coupled to the second rotor arm. The bail reversing mechanism inverts the fishing line guiding mechanism to line casting or line winding positions. The line roller is disposed on the first bail support member and the bail reversing mechanism is disposed inside the second rotor arm. The first rotor arm includes two support legs extending forwardly from an outer peripheral portion of the cylindrical portion.本發明之課題係提供一種具有使反轉機構自設置有線輥一側之轉子臂移動而使重量輕量化之轉子之釣具用捲線器。 本發明之釣具用捲線器具備:轉子120,其具有圓筒部121、與配置於圓筒部121之相互對向之位置之第1轉子臂210與第2轉子臂220;釣線引導機構2;及導線環反轉裝置30,其將釣線引導機構2區分為釣線釋放位置與釣線捲取位置。線輥3配設於第1導線環支持部21,導線環反轉裝置30配設於第2轉子臂220內部;第1轉子臂210具有自圓筒部121之外周向前方延伸之第1支持腳211與第2支持腳213。2‧‧‧釣線引導機構3‧‧‧線輥21‧‧‧第1導線環支持部22‧‧‧第2導線環支持部22a‧‧‧第1端部23‧‧‧導線環23a‧‧‧第1端部23b‧‧‧第2端部24‧‧‧支持軸30‧‧‧導線環反轉裝置120‧‧‧轉子121‧‧‧轉子本體部(圓筒部)126‧‧‧後端部(開口端)129‧‧‧平衡調整部129a‧‧‧板材210‧‧‧第1轉子臂211‧‧‧第1支持腳213‧‧‧第2支持腳220‧‧‧第2轉子臂
