PROBLEM TO BE SOLVED: To make it possible to maintain a grafting function for a required period of time even under a scorching sun.SOLUTION: A grafting tool is formed into a cylindrical-shaped cylinder body 1A which is injection-molded by plastic having appropriate elasticity, i.e., EVA (ethylene vinyl acetate). A slit 11 in vertical directions reaching from an outer peripheral surface 2 to an inner peripheral surface 3 of the cylinder body 1A is formed on one side of the body, which is constituted in an approximately C-shape in a cross-sectional view as a whole. Particularly, the body is allowed to include a constitution that positions of the center points of an outer circumferential circle 21 and an inner circumferential circle 31 of the approximately C-shape in a cross-sectional view are made different and two sides directed to one side of the slit 11 become narrower, and have a constitution that a thickness of areas other than a tip portions 4 being the narrowing two sides is formed thicker than a thickness w of the tip portions 4 to make a base portion 5 have the maximum thickness W.COPYRIGHT: (C)2014,JPO&INPIT【課題】炎天下でも必要期間にわたって接ぎ木の機能を維持可能にする。【解決手段】接ぎ木具を、適度な弾性を有するプラスチック、例えば、EVAで射出成形した円筒形の筒形体1Aとし、その一側に、筒形体1Aの外周面2から内周面3に達する上下方向の割れ目11を形成し、全体として断面視略C形状にして構成し、特に、断面視略C形状の外周円21と内周円31の中心点を異ならせて、割れ目11の一側に向かう2辺が先細る構造を備えさせ、先細る2辺である先端部4の厚みwよりも、それ以外の部分の厚みを太く形成して基部5で最大厚Wとなる構造を有するようにした。【選択図】図1
