PROBLEM TO BE SOLVED: To eliminate such a risk that an arm bar might break due to metal fatigue, by obviating the necessity of bending the arm bar repeatedly to use.SOLUTION: A plurality of arm bars to which leaders are connected, are attached to a head 1, and each arm bar includes a bar body 11 which has a connector to connect a leader and a hooking rod 13 bent via a bend 12 from the bar body 11. The head 1 is provided with a capsule 3 in which the hooking rod 13 is inserted and held. Since the bend 12 is formed in advance in the arm bar which has the bar body 11 to which the leader is connected and the hooking rod 13 bent via the bend 12 is held in the capsule 3 of the head 1, the direction of the bar body 11 to the head 1 is determined by an intersection angle that the bar body 11 and the capsule 3 makes at the preformed bend 12.COPYRIGHT: (C)2013,JPO&INPIT【解決手段】ハリスが連結される複数本の腕棒を頭部1に取り付け、腕棒にはハリスが連結される接続金具を有する棒本体11と棒本体11に対し屈曲部12を介して折り曲げられた引掛棒13とを備え、頭部1には引掛棒13が挿入されて保持される筒部3を設けている。ハリスが連結される棒本体11を有する腕棒に予め屈曲部12を形成してその屈曲部12を介して折り曲げられた引掛棒13を頭部1の筒部3に保持したので、頭部1に対する棒本体11の向きは、予め形成された屈曲部12で棒本体11と筒部3とがなす交差角度により決まる。【効果】腕棒を繰り返し折り曲げて使用する必要はなく、腕棒が金属疲労により折損するおそれはなくなる。【選択図】図2
