PROBLEM TO BE SOLVED: To provide a cushion body for the knee that is simply, easily, and inexpensively mass-produced, and allows a user to comfortably walk by elastically pressing a bent knee joint from the back, and a support for the knee including the cushion body.SOLUTION: A cushion body 1 used by being inserted between the back side of a knee and a cylindrical supporter body 10 with elasticity in which the knee is inserted, includes a plurality of elastic blocks 3 connected in the longitudinal direction. The plurality of elastic blocks 3 include, in a linear alignment, ring-shaped gaps 8 between the adjacent elastic blocks, with central parts coming into local contact with one another, outside contact parts 7. Further, in a bent-shape alignment, the elastic blocks have elasticity of elastically deforming facing surfaces of the ring-shaped gaps 8 into a shape being in close contact with one another. In the bent-shape alignment, restitutive force of energizing the elastic blocks 3 from the bent-shape alignment to the linear alignment is applied thereto by repulsive force of the elastic blocks.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】簡単かつ容易に、しかも安価に多量生産でき、しかも曲げた膝関節を裏から弾性的に押圧して、楽に歩行できる膝用のクッション体とこのクッション体を備える膝用のサポータを提供する。【解決手段】 膝の裏側と、膝を挿入する伸縮性のある筒状のサポータ本体10との間に入れて使用されるクッション体1は、長手方向に連結している複数の弾性ブロック3を備え、複数の弾性ブロック3は直線状配列において、隣接する弾性ブロックとの間に、中心部を局部的に接触して、接触部7の外側にリング状隙間8を設けており、さらに屈曲状配列においてはリング状隙間8の対向面を互いに密着させる形状に弾性変形する弾性を有し、屈曲状配列において弾性ブロック3の反発力でもって屈曲状配列から直線状配列の方向に付勢する復元力を作用させる。【選択図】図1
