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. |
