PROBLEM TO BE SOLVED: To provide a fishing float whose functions as a center pierced float and a float with a ring are convertible, in which there is no need to attach and detach an adaptor, which is produced without much trouble, and which a fishing line hardly gets twisted around.SOLUTION: A cylindrical part 9 which attaches to, protrudes from and is rotatable around the penetration hole 5 is equipped at a lower end of the penetration hole 5 which longitudinally penetrates the float body 3 and allows the fishing line 7 to insert in. The cylindrical part 9 has a penetration hole 11 which penetrates crosswise and allows the fishing line to insert in. When the fishing float is used as a center pierced float, the fishing line 7 is inserted in the penetration hole 5, and when the fishing float is used as a float with a ring, the fishing line 7 is inserted in the penetration hole 11.COPYRIGHT: (C)2012,JPO&INPIT【課題】中通し浮子と環付き浮子との機能を切換えて使用でき、アダプターを脱着する必要がなく、浮子の製造が面倒でなく、浮子に釣り糸が絡みついてしまう可能性が少ない釣り用浮子を提供する。【解決手段】浮子本体3を上下に貫通し釣り糸7を挿通できる挿通孔5の下端に、連通して、突出し、貫通孔5軸周りに回転可能な円筒部9を設ける。この円筒部9に左右に貫通し釣り糸を挿通できる貫通孔11を有する。中通し浮子として使用するには、釣り糸7を挿通孔5に挿通すればよい。環付き浮子として使用するには、釣り糸7を貫通孔11に挿通すればよい。【選択図】図1
