[Challenge] At a fishing using a live bait and kneading bait, it rotates in water, to collect the fish of attention is visible to insects, to provide fishing improvement tool fishing can be significantly improved. The invention relates to a fishing improved tool T to be removably secured to the fishing line S with a needle for feeding a main body 2 made of a hollow square-shaped spring plate 1 of elongate vertically, one length of the main body 2 It has a number of the comb teeth 5 which is projecting toward the other long side 4 from the side 3,. Comb tooth is beyond the other long side 4, the tip 6 of the comb teeth 5 is a small protruding. It has a bulging head 7 at the distal end 6 of the comb teeth 5. Body 2, and an elastically deformed alternately in side view lateral direction opposite to the arcuate, At a one of the left arcuate or right arcuate, the fishing line S, pressure held by the main body 2 and the comb teeth 5 and it is configured to. .BACKGROUND 2【課題】生き餌や練り餌を用いる魚釣りに於て、水中で回転し、ムシに見えて魚の注目を集め、釣果が著しく向上する釣果改善具を提供する。【解決手段】餌付け用の針を有する釣り糸Sに着脱自在に固着される釣果改善具Tであって、縦方向に細長のロ字状のバネ板1から成る本体2と、本体2の一長辺3から他長辺4に向かって突設された多数のクシ歯5と、を有する。クシ歯5は他長辺4を越えて、クシ歯5の先端6が小さく突出状である。クシ歯5の先端6に膨出頭部7を有する。本体2は、側面視左右逆方向に交互に弓状に弾性変形自在であって、左弓状又は右弓状のいずれかに於て、釣り糸Sを、本体2とクシ歯5にて圧接保持するように構成する。【選択図】図2
