PROBLEM TO BE SOLVED: To provide a bead that can simply mount a branch line and dismount it at low cost by providing a groove for mounting the branch line in the bead made of metal or resin, and furthermore enables the branch line attached with a fishhook to draw an arc on the top without rotation being a Japanese tradition and the fishing catch may be increased to thereby bind a trunk line with the branch line.SOLUTION: A bead is characterized in that a through hole for penetrating a trunk line and a groove for tightening a branch line in the right angle direction are present. Also, a shape of the groove is characterized in that the one going to the inside of the bead is narrowed, and the groove spreads out toward the outer circumference of the bead. A line for forming the groove is characterized in that one is flat and another line becomes a slanting line to intersect in the direction going to the inside of the bead.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 樹脂若しくは金属で形成されたビーズに枝糸を取り付ける溝を設けることにより、安価で枝糸の取り付け、取り外しが簡単に出来、しかも日本の伝統でもあり釣果もあがると言われる釣り針を付けた枝糸が回転する事なく上に弧を描くことを可能とする、幹糸と枝糸を結束させるビーズを提供する。【解決手段】 幹糸を通す貫通穴と直角方向に枝糸を締付ける溝がある事を特長とする。また溝の形状はビーズの中に向う方は狭まり、ビーズの外周に向っては溝が広がっていく事を特徴とする。溝を形成するラインはー方は水平であり、もう1つのラインが斜線となりビーズの中に向う方向で交わる事を特徴とする。【選択図】図1
