< Topic >You can obtain the revolution which is stabilized at high speed, when especially, the water flow is weak, when the water flow hits diagonal, when the propeller is small and the like, the propeller for the fish fishing lure where revolution becomes good in is offered.SolutionsWall surface or difference in level 2 is provided on blade 4 of the propeller. Difference in level 2 is made as the form which bends to crank condition as the manner which provides wall surface or difference in level 2, blade 4 considered as the edge strip. There is also a manner which provides the projection of fin condition on the blade 4 aspect. In case of the blade 4 which has thickness, it shaves near axial hole and 1 it is possible to provide difference in level 2 by the fact that it is packed. It faces vis-a-vis the blade 4 aspect approximately verticality it is not, axial hole 1 as a symmetrical center in order approximately to become parallel, it lays out the upright surface which it occurs with wall surface or difference in level 2, with two deck. It uses with the kind of direction where the water flow hits to the dent.< Choice figure >Drawing 1【課題】高速で安定した回転が得られ、特に、水流が弱い場合、水流が斜めに当たる場合、プロペラが小さい場合などにおいても回転が良くなる魚釣りルアー用プロペラを提供する。【解決手段】プロペラのブレード4上に壁面ないし段差2を設ける。壁面ないし段差2を設ける方法としては、ブレード4を側面から見てクランク状に折り曲げた形状として段差2を作る。ブレード4面上にフィン状の突起を設ける方法もある。厚みのあるブレード4の場合、軸穴1の付近を削り込むことで段差2を設けることができる。壁面ないし段差2により生じた直立面は、ブレード4面に対しておよそ垂直をなし、軸穴1を対称の中心として向き合い、およそ平行になるように二つ一組で配置する。水流がその凹みに当たるような向きで用いる。【選択図】図1
