Problem to be solved: to provide a supporter with good mounting feeling.The supporter comprises a mounting portion 10 which can be mounted on the movable part of the body and an elastic body 40 provided in the mounting portion. The elastic member 40 includes a plate-like first member 41 and a second member 42, which is softer than the first member 41, and is located on the movable site side as viewed from the first member 41. The knee portion is supported by elastically pressing the side of the knee portion in the mounting state.Elastic deformation by bending of the knee and resiliently restored at extension of the knee.Diagram【課題】装着感が良好なサポーターを提供する。【解決手段】サポーターは、身体の可動部位に装着可能な装着部10と、装着部に設けられた弾性体40とを具備する。弾性体40は、板状の第1部材41と、第1部材41よりも軟質であり、第1部材41からみて可動部位側に位置する板状の第2部材42とを含む。装着状態において膝部の側面を弾性的に押圧することで当該膝部を支持する。膝部の屈曲により弾性的に変形し、膝部の伸展時に弾性的に復元することで膝部の伸展を補助する。【選択図】図4
