To provide The present invention is a simple attachment to the road yarn float flying time locking device. A float flying during the locking device 103, curved cylindrical upstream end and a center Michi-ito insertion hole 18a formed the cylindrical pipe diameter larger than the outer diameter of the pipe 17 Kakaritome-dama 18 or is, float stopper ball 19 is larger in diameter than the outside diameter of the cylindrical pipe 17 formed with Michi-ito insertion hole 19a in the center to the downstream end of the curved tubular pipe or, , it includes the both. Cylindrical pipe 17 is made from a flexible member, the inner diameter of the road thread insertion hole 18a of Kakaritome-dama is smaller is better on the upstream side of the inner diameter than the downstream side, the inner diameter of the road thread insertion hole 19a of the float stop ball Preferably, the larger the downstream side of the inner diameter than the upstream side.BACKGROUND 3【課題】道糸への取付が簡単なウキ飛翔時係止具を提供する。【解決手段】ウキ飛翔時係止具103は、湾曲した筒状パイプ17の上流側の端部を中心部に道糸挿通孔18aを形成した筒状パイプの径より大きい外径である係止玉18、または、湾曲した筒状パイプの下流側の端部に中心部に道糸挿通孔19aを形成した筒状パイプ17の外径より大きい径であるウキ止め玉19、または、その両方を具備する。筒状パイプ17は柔軟性のある部材からなり、係止玉の道糸挿通孔18aの内径は、下流側よりも上流側の内径の方が小さく、ウキ止め玉の道糸挿通孔19aの内径は、上流側よりも下流側の内径の方が大きいことが好ましい。【選択図】図3
