Problem to be solved: to provide a knee mounting device capable of imparting an abutment force to the flexor muscle group contributing to the bending of the knee in the area from the lower leg to the thigh.Solution: the knee fitting member 100 is provided with a cylindrical body 20 mounted in a region extending from the lower leg to the thigh with the knee 36 interposed therebetween, and a belt like portion 10 provided in the cylindrical body 20 and having a stretchable degree so as to abut against a predetermined position when mounted on the leg 30. The strip portion 10 extends from the lower leg to the thigh and passes through the knee 36, and is provided so that the abutment force can be applied to the flexor muscle group contributing to the bending of the knee 36.Diagram【課題】下腿部から大腿部にわたる領域で膝の屈曲に寄与する屈筋群に当接力を付与可能な膝装着具を提供する。【解決手段】膝装着具100は、膝36を挟んで下腿部から大腿部にわたる領域に装着される筒状体20と、筒状体20に設けられ、脚30に装着されたときに所定の部位に当接する程度の伸縮性を有する帯状部10と、を備える。帯状部10は、下腿部から膝36を通り大腿部にわたって延伸し、膝36の屈曲に寄与する屈筋群に当接力を付与可能に設けられる。【選択図】図1
