To provide a protective color for animals which is large in size adjustment, light in weight, compactly storable, easy to carry and inexpensive.SOLUTION: In using the animal protective collar 1, by selecting the slit 9 into which the insertion tongue pieces 6, 7 are inserted, the diameter of the annular inner peripheral portion 2 according to the size of the animals to be applied around the neck Can be adjusted. By adjusting the angle of crease of the fold 8, the diameter of the annular outer peripheral portion 3 is changed, so that the opening angle of the conical base can be adapted to the size of the head of the animal. The insertion tongue piece projects from the first and second both end edges 4 and 5 respectively, and since the insertion tongue piece can be inserted into the slit from the inside and the outside of the conical base to be locked during assembly, the shape is stably maintained .BACKGROUND OF THE INVENTION【課題】寸法の調整代が大きく、軽量で、コンパクトに収納でき、持ち運び容易で安価に得られる動物用の保護カラーを提供する。【解決手段】動物用保護カラー1は、その使用に当たり、差し込み舌片6,7を差し込むスリット9を選択することにより、適用する動物の首周りの大きさに応じ、環状内周縁部2の径を調整できる。折目8の折角度を調整すれば、環状外周縁部3の径が変わり、円錐台筒の開き角度を動物の頭部の大きさに適合させることができる。第1、第2の両端縁4,5からそれぞれ差し込み舌片が突出しており、組立時に差し込み舌片を円錐台筒の内側と外側からスリットに差し込み係止できるので、形状が安定的に維持される。【選択図】図1
