The present invention utilizes the bristles of elasticity , retention of Ikadzuno , to provide a compact Ikadzuno up device having excellent light weight and ease of processing that indicates the effect on. A is flocked the brush up and down the inner surface of the shaped rectangular body 2 of substantially U , the upper and lower brushes 3 and 4 , is held across multiple Ikadzuno 12 which are coupled in series , is turned on , gimmicks yarn 14 and throwing the weights 13 attached to the tip into the sea , away from the brush to more Ikadzuno a chain in its gravity , it is Ikadzuno up device for spontaneous emission . The lower front of the shaped rectangular body of substantially U , upon release of Ikadzuno , so as not to catch under the brush and the boat side 16 , is preferably provided with a sliding block 8 to the slid Ikadzuno . [ Selection Figure ] Figure 1【課題】ブラシ毛の弾力性を利用し、イカヅノの保持、投入に効果を示す軽量性と加工容易性に優れた小型のイカヅノ投入器を提供する。【解決手段】略コの字状長方体2の上下内面にブラシを植毛し、その上下ブラシ3,4により、直列に連結した複数のイカヅノ12を挟んで保持し、投入は、仕掛け糸14の先端に取付けた錘13を海中に投げ入れ、その重力で複数のイカヅノが連鎖してブラシから離れ、自然放出するイカヅノ投入器である。略コの字状長方体の下部前面に、イカヅノの放出時、下ブラシ及び船縁16に引っかからないように、イカヅノを滑らすための滑走台8を具備するのが好ましい。【選択図】図1
