PROBLEM TO BE SOLVED: To provide a nose ring for cattle, capable of improving the operability of attachment to the nasal septum of the cattle by facilitating the insertion of a pricking rod into a binding part, and hardly allowing the pricking rod to be separated from the binding part after the attachment because an outward force can be converted to a binding force to the binding part even when the outward force acts on the pricking rod.SOLUTION: The nose ring for the cattle obtained by installing a pricking rod 2 in one terminal of a C-shaped loop 1 composed of an elastic body, and the binding part 3 to be engaged with the pricking rod 2 in the other terminal is obtained by forming the tip of the pricking rod 2 into an arrowhead-shaped part 4, installing an engaging stepped part 5 in the base part of the arrowhead-shaped part 4, forming an opening by removing at least one side face of the binding part 3, forming an insertion hole 6 for the insertion of the pricking rod 2, forming the right and left side faces and the upper or lower face of the insertion hole 6 into tilted parts corresponding to the tilted faces in a conical shape of the pricking rod 2, and protruding an engaging protrusion 7 to be engaged with the engaging stepped part 5 at the side of the pricking rod 2 from the inner wall of the insertion hole 6 so as to form a U shape.COPYRIGHT: (C)2010,JPO&INPIT【課題】穿刺杆を結合部に挿入しやすくして牛の鼻中隔への装着の作業性を向上でき、装着後は、穿刺杆に外方への力が作用してもこれを結合部に対する結合力に変換でき穿刺杆が結合部から抜けにくい牛の鼻輪を得る。【解決手段】弾性体よりなるC字状環体1の一端に穿刺杆2を設け、他端に前記穿刺杆2が係止する結合部3を設けた牛の鼻輪において、前記穿刺杆2の先端を矢尻状部4に形成し、この矢尻状部4の基部に係止段部5を設け、前記結合部3は少なくとも1面側面を欠損して開口に形成するとともに、前記穿刺杆2が挿入する挿入孔6を形成し、該挿入孔6は左右側面および上または底面を穿刺杆の円錐形の傾斜面に対応するような傾斜部に形成し、この挿入孔6の内壁から前記穿刺杆2側の係止段部5が係止する係止突片7をU字形にして突設した。【選択図】 図1
