PROBLEM TO BE SOLVED: To provide an attaching tool of a cow nose ring which reduces weight, enhances usability, is free from a risk that a pivotal fitting part damages a rod body when a pair of rods is pivotally fitted with each other in a center part and formed into a scissors-shape, and can obtain a smooth rotation without friction resistance.SOLUTION: The attaching tool of a cow nose ring includes a connection cylinder having a larger diameter including: a piercing rod in an arrowhead shape at one end of a C-shaped annular body made of an elastic body and a fitting hole to be fitted with the piercing rod, at the other end. A pair of rods 7a, 7b is pivotally fitted with each other in a center part and formed into a scissors-shape, the pair of rods 7a, 7b is made of an aluminum alloy or synthetic resin, and a mutual pivotal fitting part 10 in a center is constituted by: a synthetic resin hollow pipe 22 as an axis a bolt 23 penetrating the synthetic resin hollow pipe and a nut 24 screwed at a tip of the bolt 23.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】軽量化でき、使い勝手が向上するとともに、一対の杆の中央部を相互に軸着して鋏状に形成する場合に軸着部が杆本体を傷めるおそれがなく、しかも、摩擦抵抗なくスムーズな回動が得られる牛の鼻輪の取付具を提供する。【解決手段】弾性体よりなるC字状環体の一端に矢尻状の突刺杆を設け、他端に前記突刺杆が係止する嵌合孔を有する拡径の結合筒部を設けた牛の鼻輪の取付具であって、一対の杆7a、7bの中央部を相互に軸着して鋏状に形成し、一対の杆7a、7bはアルミ合金もしくは合成樹脂で作製し、中央部の相互軸着部10は、軸となる合成樹脂製中空管22とこれを貫通するボルト23および該ボルト23の先端に螺合するナット24で構成した。【選択図】図1
