PROBLEM TO BE SOLVED: To provide a knee joint brace capable of reducing a burden on the front surface side of a knee joint even when a large load is applied to the front surface side of the knee joint in a state where a knee is nearly stretched.SOLUTION: A knee joint brace includes: a thigh-side mounting part 2 to be mounted on a thigh on the upper side of a knee joint A a lower-leg-side mounting part 3 to be mounted on a lower leg on the lower side of the knee joint A a pair of connection parts 4 for turnably connecting rear sides of the lower-surface-side intermediate part of the thigh-side mounting part 2 to rear sides of the upper-surface-side intermediate part of the lower-leg-side mounting part 3 on both right and left sides of the knee joint A a first projection 2b formed at a front-side lower end of the thigh-side mounting part 2 and a second projection 3b formed at a front-side upper end of the lower-leg-side mounting part 3 so as to face the first projection 2b. The first and second projections 2b and 3b come into contact with each other just before the knee is substantially fully stretched in walking in a state where the thigh-side mounting part 2 and the lower-leg-side mounting part 3 are mounted on the thigh and the lower leg respectively.COPYRIGHT: (C)2014,JPO&INPIT【課題】膝が略伸びた状態となって膝関節の前面側に大きな荷重がかかるような場合でも、膝関節の前面側への負担を軽減することができる膝関節装具を提供する。【解決手段】膝関節Aの上側の大腿部に装着される大腿部側装着部2と、膝関節Aの下側の下腿部に装着される下腿部側装着部3と、膝関節Aの左右両側で、大腿部側装着部2の下面側中間部よりも後側と下腿部側装着部3の上面側中間部よりも後側とを回動可能に連結した一対の連結部4と、大腿部側装着部2の前側下端部に形成された第1の突起部2bと、下腿部側装着部3の前側上端部に第1の突起部2bと対向するようにして形成された第2の突起部3bとを備え、大腿部側装着部2と下腿部側装着部3がそれぞれ大腿部と下腿部に装着された状態で、歩行時に膝が略伸びきる手前で第1、第2の突起部2b,3b同士が当接されるようにした。【選択図】図1
