< Topic >Making use of the principle of the lever and the pulling power of the spring, in order curvature movement the legs safely, while assisting, it offers the health equipment which assures healthy maintenance increase with curvature movement.SolutionsThe frame 1 which does seesaw motion when axial support it is done and, it consists of in support 3 the support the vertex of 3 which stand facilities is done and support 3 as a fulcrum on stand 2, as for frame 1, it can install the coiled tensile spring 5 which, is locked to stand 2 to one end, by the fact that the having hand 4 which the user holds down by the hand is installed, it has and in the other edge the vertex of support 3 as a fulcrum, the health equipment which features that the seesaw motion where the hand 4 moves up and down is done.< Selective figure >Figure 1【課題】てこの原理と、バネの引張力を利用して、下肢の屈曲運動を安全に行えるように補助しつつ、屈曲運動によって健康の維持・増進を図る健康器具を提供する。【解決手段】台2上に立設する支柱3と、支柱3の頭頂部を支点として支柱3に軸支された状態でシーソー運動をするフレーム1と、からなり、フレーム1は、一端に、台2に固定されたコイル状の引張バネ5が取り付けられ、他端には、使用者が手で押さえる持ち手部4が取り付けられていることで、支柱3の頭頂部を支点として、持ち手部4が上下に動くシーソー運動をすることを特徴とする健康器具。【選択図】図1
