PROBLEM TO BE SOLVED: To provide a self-standing supporting tool for a seedling that enables a support portion to follow a stem as the stem increases in height and that can easily and reliably hold the stem in a gripping portion without damaging the stem.SOLUTION: A support rod 2 is stood near a seedling A, with the support rod 2 passed through a ring portion 4 of a body 3. A finger is put on an operating protruding piece 7, with the gripping portion 6 is directed to the stem of the seedling A, to deform the gripping portion in such a manner as to elongate the curve of the gripping portion 6, so as to widely open a crevice 8 and receive the stem of the seedling A inside the gripping portion 6. With the stem in contact with the inner periphery of the gripping portion 6 elongated, the finger is released form the operating protruding piece 7, whereby the gripping portion 6 is restored to its annular shape and grips the stem with an appropriate gripping force. As the stem grows and its gripped part moves upward, the ring portion 4 moves reasonably upward relative to the support rod 2 and follows the gripped part.COPYRIGHT: (C)2013,JPO&INPIT【課題】茎丈の伸長に応じて支持部を追従させることができ、また、茎を傷つけることなく容易かつ確実に把持部に保持することができる幼苗の自立支持具を提供する。【解決手段】本体3のリング部4に支持棒2を挿通した状態で、幼苗Aの傍らに支持棒2を立てる。把持部6を幼苗Aの茎に向け、操作突片7に指を掛け、把持部6の湾曲を伸ばすように変形させて割れ目8を大きく開き、把持部6の内側に幼苗Aの茎を受け入れる。引き延ばした把持部6の内周に茎を接触させた状態で、操作突片7から指を離すと、把持部6が環状に復元して、適度の把持力で茎を把持する。苗が生長して把持部分が上方へ移動すると、リング部4が支持棒2に対して上方へ無理なく移動して、これに追従する。【選択図】図1
