PROBLEM TO BE SOLVED: To provide a thread-hanging auxiliary tool whhich can be appropriately used for hanging vine crops such as green pepper.SOLUTION: The thread-hanging auxiliary tool includes a semicircular stem supporting part for supporting a stem, and an approximately V-shaped thread holding part extending from the stem supporting part. A V-shaped cut is formed at the distal end of the thread supporting part, and a slit in a prescribed length for holding a thread material is formed in the base of the V-shaped cut. The semicircular stem supporting part is formed thinner than the thread holding part, and can be reamed as the stem grows.COPYRIGHT: (C)2012,JPO&INPIT【課題】ピーマンなどの蔓作物の糸吊り作業に好適に使用できる糸吊り補助器を提供する。【解決手段】茎を支持する半円弧状の茎支持部と、該茎支持部から延出した略レ字形状の糸挟持部とから構成され、該糸支持部の先端にはV字形の切込みが形成されると共に、該V字形の切込み基部には糸材を挟持するスリットが所定の長さで形成され、且つ前記半円弧状の茎支持部は、前記糸挟持部より肉薄に形成され茎の成長に伴ない拡径可能とする。【選択図】図1
