PROBLEM TO BE SOLVED: To provide a lure floated in water without floating up to the water surface, even if it is formed into a relatively large size, and it may be caused to dynamically swim, while drastically swinging a caudal fin, by reducing a water resistance dynamically especially in a transverse direction, thereby improving a fish-luring effect.SOLUTION: An outer fence 4 enclosing an interior space S forms the trunk 5 of a skeleton 1 so that at least the right and left side parts 4a and 4b of said outer fence 4 are opened to cause the interior space S to communicate over its entirety with the outside.COPYRIGHT: (C)2016,JPO&INPIT【課題】比較的大型に形成されたとしても水上に浮き上がることもなく、水中に浮遊させられ、特に左右方向の水の抵抗を飛躍的に軽減して尾びれを大きく振って躍動的に遊泳させられる様にして集魚効果を向上させたルアーを提供する。【解決手段】内部空間Sを囲繞する外郭4にて躯体1の胴部5を形成し、前記外郭4の少なくとも左右側部4a、4bは、その全体にわたって内部空間Sを外部に連通する様に開設する。【選択図】図1
