PROBLEM TO BE SOLVED: To provide a leader stopper capable of preventing a leader from easily coming off while reducing a case of the line getting tangled up, and that allows easy attachment and the like of the leader itself thereto.SOLUTION: A leader stopper for angling, includes a trunk part having a through hole for inserting a trunk line and the like, and a hook part for hooking a leader. The hook part is provided with a guide path including an opening for inserting an end of the leader, and an opening from which the end of the inserted leader is drawn out. Further, a slit communicated with the guide path is cut from a position farthest from the trunk part of the opening from which the end of the leader is drawn out, toward the opening for inserting the end of the leader. A length of the slit is set to be longer than a distance from an end of the slit on a side of the opening for inserting the end of the leader to the guide path, along a communicating surface of the opening and the guide path (a hooking length of the leader).COPYRIGHT: (C)2014,JPO&INPIT【課題】ハリスが外れ難い一方で糸の絡まりが少なく、ハリスそのものの取り付け等を簡便に行うことができるハリス止め具を提供する。【解決手段】幹糸等を通すための通し孔を有する胴体部とハリスを掛止するための掛止部とを備えた釣用ハリス止め具であって、前記掛止部には、前記ハリスの端部を挿入するための開口を備えた誘導路と、前記挿入された前記ハリスの端部が抜け出す開口とが設けられ、前記ハリスの端部が抜け出す開口のうち、前記胴体部から最も遠い位置から前記ハリスの端部を挿入するための開口へ向かって、前記誘導路と連通するスリットが切り込まれ、前記スリットの長さは、前記スリットの、前記ハリスの端部を挿入するための開口側の端部から前記誘導路までの距離(ハリスの掛かり長さ)よりも長くなるように構成されたことを特徴とするハリス止め具。【選択図】図1
