The present invention relates to a game for preventing joint contracture and increasing muscular strength, which has a function of a ball moving in order in the vertical direction in conjunction with leg or hand bending, extension movement, and leg raising / lowering movement. It aims at providing the rehabilitation instrument which has property. SOLUTION: A backflow prevention valve 19a for preventing a ball from falling downward, a ball storage box 14 in which balls 13 are aligned in a vertical row, and a vane plate 11 are swung in conjunction with a bending or extending movement of a foot or a hand. The game and muscle strength are devised so that the ball 13 stationary at a predetermined position of the inclined plate 16 can be moved in a certain direction in order by the number of movements by the vertical movement of the push-up bar 18 interlocked with the swing of the blade plate 11. We have devised a rehabilitation device that also has ups. [Selection] Figure 1【課題】本発明は、足または手の屈曲と伸展運動と脚の上げ下げ運動に連動して、ボールが鉛直方向に順番に移動する機能を有する関節の拘縮防止と筋力アップを目的としたゲーム性を有するリハビリ器具を提供することを目的とする。【解決手段】ボールの下方落下を阻止する逆流防止弁１９ａと、ボール１３が鉛直一列に整列されるボール収納箱１４と、足または手の屈曲伸展運動に連動して羽根板１１を揺動させ、羽根板１１の揺動に連動した押し上げ棒１８の上下動によって傾斜板１６の所定位置に静止するボール１３を運動回数分だけ順番に一定方向にだけ移動できるように工夫した、ゲーム性と筋力アップも兼ね備えたリハビリ器具を考案した。【選択図】図１
