The present invention has a simple structure, it is not necessary to tension yarns by human power is twisted tightly, easily bundled, packing time is also reduced, the user is spread more easily tension yarn when you use, good usability, to provide a wound of the tension thread for thread not also become entangled bird net. Includes A strip-shaped plate main body 2, the groove 3 of the W-shaped is processed symmetrically at both ends of the plate body 2, the ends of the plate body 2 adjacent to the groove 3 is a convex tooth 1 . Convex tooth 1 is a structure of arched. The plate body 2 trees, made of plastic or paper.FIELD 1【課題】構造が簡単で、人力で張り糸がきつくねじられる必要がなく、簡単に束ねられ、梱包時間も削減され、使う時にユーザーがより容易に張り糸を広げ、使い勝手がよく、糸も絡まらない防鳥網用張り糸の糸巻きを提供する。【解決手段】帯状の板本体2を含み、板本体2の両端にW形の溝3が対称に加工され、溝3と隣り合う板本体2の端部は凸歯1である。凸歯1はアーチ形の構造である。板本体2は木、プラスチック又は紙で作られる。【選択図】図1
