To provide a mechanism to fly in a stable state with the direction of flight of the in-process parts always facing forward when throwing in-process parts such as the omnibus, scales, baskets, comet cages and floats.SOLUTION: A hook portion 4 is provided in front of a part existing in front of a work in process, a catch ring 2 provided on a warp thread 3 is engaged with the hook portion 4, and components are connected at the time of inputting acceleration, and then the hook portion 4 And the sling 2 disengages, and thereafter, it pulls the lanyard 3 by the warp thread ring 7 provided at the rear part of the part, and flies forward stably without flipping or fluttering of parts during flight.BACKGROUND OF THE INVENTION【課題】オモリや天秤・カゴ・コマセカゴ・浮き等の仕掛部品を投入する際に、仕掛部品の飛行の方向が、常に前方に向いた状態で、安定した状態で飛行する仕掛けを提供する。【解決手段】仕掛投入時に前方に有る部品の前方に鈎部4を設け、これに道糸3に設けた掛輪2を着合うし、仕掛け投入加速時に部品を繋引した後、鈎部4と掛輪2が離脱して、その後、部品後部に設けた道糸環7により道糸3を引行し、飛行中に部品の反転や動揺が無く前方に安定して飛行する。【選択図】図1
