PROBLEM TO BE SOLVED: To sufficiently ensure repelling effects by habits of animals such as keeping away from an artificial artifact as well as to avoid trouble in coming off of a tool for preventing animal injury for trees from a tree.SOLUTION: There is provided: the tool 1 for preventing the animal injury for trees having an engageable band part 2 provided on the side of one end and an engaging band part 3 for inserting the engageable band part 2 by providing the engaging band part 3 on the side of the other end, and having one or two or more longitudinal slot parts 4a, ... formed in the short side direction Ds to engage with the inserted engageable band part 2. When the tool 1 for preventing the animal injury for trees in which the whole is integrally formed so that winding around the tree T can be carried out is composed, the engageable band part 2 and the engaging band part 3 are formed of a sheet material S using a flexible material, and a tensile load F having a prescribed magnitude or more is applied to one or both of long sides 2u and 2d in the engageable band part 2 during engaging of the engageable band part 2 with the longitudinal slot parts 4a, ... to thereby sequentially form a plurality of uneven parts 6m, ... and 6v, ... wherein the longitudinal slot parts 4a, ... allow the engageable band part 2 to pass through the longitudinal slot parts 4a, ... in the long side direction Dm.COPYRIGHT: (C)2013,JPO&INPIT【課題】 人為的な造作物には近寄らないという獣類の習性による忌避効果を十分に確保することに加え、樹木用獣害防止具が樹木から外れる不具合を回避する。【解決手段】 一端側に設けた被係止バンド部2と、他端側に設けることにより、被係止バンド部2を挿入し、かつ挿入した当該被係止バンド部2を係止する短辺方向Dsに形成した一又は二以上の縦長孔部4a…を有する係止バンド部3とを備え、全体を樹木Tに巻付け可能に一体形成した樹木用獣害防止具1を構成するに際して、被係止バンド部2及び係止バンド部3を、柔軟性素材を用いたシート材Sにより形成するとともに、被係止バンド部2における長辺2u,2dの一方又は双方に、縦長孔部4a…に対する被係止バンド部2の係止時に所定の大きさ以上の引張荷重Fが付加されることにより被係止バンド部2が縦長孔部4a…を通過可能な複数の凹凸部6m…,6v…を長辺方向Dmに順次形成する。【選択図】 図1
