< Solution topic >It designates that the shark repulse device for fishing industry which as for this invention, at the same time, can be able keep the distance between the electrodes which impress voltage without ruining the efficiency of the fishing tool, in regular fixed distance expand the shark evasion effect to wide scope is offered as solution topic. SolutionsThe arm which the pair of scales (1) has (11) the 1st electrode (21), and the 2nd electrode (22) you install this invention, on the both ends, without ruining the efficiency of the fishing tool the power source section which functioning is done (23) the spindle section which is received (14) by installing, the arm (11) as the electric power supply section medium time, both electrodes (21,22) distance between uniformly because it is possible, usual to maintain, you can expand the shark evasion effect to wide scope. < Selective figure >Figure 1【解決課題】本発明は,漁具の性能を損なうことなく,電圧を印加する電極間の距離を常時一定距離に保持することができ,かつ,鮫忌避効果を広範囲に広げることのできる漁業用鮫撃退装置を提供することを解決課題とする。【解決手段】本発明は,天秤(1)が備えるアーム部(11)の両端に第1の電極(21),及び第2の電極(22)を取り付け,アーム部(11)の中頃に電力供給部として機能する電源部(23)を収納した錘部(14)を取り付けることにより,漁具の性能を損なうことなく,両電極(21,22)間の距離を常時一定に保つことができるため,鮫忌避効果を広範囲に広げることができる。【選択図】図1
