An object of the present invention is in the aim was to maintain so as not to release the Komase, etc. until it reaches the shelves and it aimed at Tana after reaching it to be able to reliably release the Komase etc., simplicity of structure, prevention of failure or damage, high cost can be of suppression, I want to be able to also dispel adverse effect on the fishing. A spacing holding member 7 is provided between the upper body 3 car body 2 after the separation and separable vertically for Komase inserting the lower body 4, the upper body 3 and the lower body 4 on the separation section of each other, joined by relative rotation of the lower body 3, 4 and at the junction and coupling mechanism 12 is provided to be separated in the reverse rotation, on the outer surface of the lower body 3 and 4, on top, water resistance received during the water floating to the upper body 3 precedes with causing the rotational force of the bonding direction in the lower body 3 and 4 in the flow resistance the lower member 4 is subjected at the time of the flight time and / or water subsidence preceding, rectifying members 31 to 33 in the lower body 3 and 4 causes a rotational force in the separating direction is provided. [Selection Figure] Figure 1【課題】狙ったタナに到達するまでコマセ等を放出しないように維持し且つ狙ったタナ到達後にはコマセ等を確実に放出できるようにし、構造の簡潔化、故障や破損の防止、高コスト化の抑制が可能で、釣果への悪影響も払拭できるようにする。【解決手段】コマセ入れ用のカゴ本体2が上下に分離可能で且つ分離後の上部体3と下部体4との間に離間保持材7が設けられており、上部体3及び下部体4の互いの分離部分には上、下部体3,4の相対回転で接合しこの接合時とは逆回転で分離する連結機構12が設けられており、上、下部体3,4の外面には、下部体4が先行する飛翔時及び/又は水中沈下時に受ける流体抵抗で上、下部体3,4に接合方向の回転力を生じさせると共に上部体3が先行する水中浮上時に受ける水抵抗で上、下部体3,4に分離方向の回転力を生じさせる整流部材31~33が設けられている。【選択図】図1
