< Topic >As the root catching is prevented in the plumb bob for fishing which is used for the one for throwing fishing, when recovering the plumb bob for fishing which can be recovered easily is offered.SolutionsThe plumb bob for fishing made the plumb bob concatenate itself which provides the through hole for concatenaion on the both ends with multiple wires, or the PE make fishline was twisted on fishing line side and installed the twist resetting for preventing. In order to break off from the obstacle by the fact that the fishline is pulled strongly the plumb bob itself individual tried rises that with principle of the lever.< Choice figure >Drawing 1【課題】投げ釣り用に用いられる釣り用錘において、根掛りを防止すると共に回収時には容易に回収できる釣り用錘を提供する。【解決手段】釣り用錘は、両端に連結用の貫通穴を設けた錘本体を複数個ワイヤー又はPE製釣り糸で連結させ、道糸側にはねじれ防止のための撚り戻しを取り付けた。釣り糸を強く引くことで障害物から離脱させるために錘本体個々がテコの原理で立ち上がるようにした。【選択図】図1
