PROBLEM TO BE SOLVED: To provide a leg support brace for an animal which can be easily put on an animal, easily fits the body of the animal regardless of the difference in the body shapes, and can effectively restrain/restrict the movement of the knee joint or ankle joint of the leg, and therefore which can be firmly fastened around the joint so that the animal cannot easily take off the leg support brace when he/she tries to take it off because he/she does not like to wear it.SOLUTION: A leg support brace for an animal includes: a leg wearing member 2 which is cylindrically disposed around the part ranging from a lower leg K immediately above an ankle region S to a thigh D, passing through a knee H of the leg and a connection member 4 for attachably/detachably connecting the ends of the leg wearing member which are adjacent to each other. In the part of the leg wearing member which corresponds to the vicinity immediately above the ankle region, a belt-like part 3, which is wound around the part immediately above the ankle region of the leg in the state of firmly sticking thereto and applies compressive force to the vicinity immediately above the ankle region so that the leg wearing member is not moved, is provided.COPYRIGHT: (C)2016,JPO&INPIT【課題】動物への装着が容易で、動物の体型の違いなどにも容易に適合させ、効果的に脚部における膝関節や足根関節の動きを拘束・制限することができ、動物が嫌がって外してしまおうとしても容易に外すことができないようにしっかりと固定できるようにする。【解決手段】脚部の足根部Sの直上の下腿部Kから膝部Hを通って大腿部Dに至る部分の周りに筒状に配置される脚部装着部材2と、脚部装着部材の隣接する端部を着脱自在に連結する連結部材4とを備え、脚部装着部材のうち足根部直上付近に対応する部分には、脚部の足根部直上の周りに密着状態で巻き付けられて足根部直上付近に圧縮力を付加して脚部装着部材の保持を図る帯状部分3が設けられている。【選択図】図3
