PROBLEM TO BE SOLVED: To provide a jig for strengthening lower limb muscle force, a jig that even an older person or a physically impaired person can independently strengthen lower limb muscle force for safe and smooth walking without anybody's help.SOLUTION: The jig includes: a footrest 1 for placing a foot of a person； a first roller 3 that rotates around a shaft orthogonal to the center line which connects the toe side end part and the heel side end part of the footrest and that is arranged in the rear of the heel side end part of the footrest； and a second roller 4 that is arranged under the center part of the footrest. The first roller is formed so that it restricts movement of the footrest in a direction from the toe side end part toward the heel side end part and that it enables rotation in one direction only in a manner allowing the movement of the footrest in a direction from the heel side end part toward the toe side end part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】歩行を安全かつ円滑に行うための下肢筋肉を、高齢者や障碍者であっても人手を要することなく自立的に強化することができる下肢筋力の強化冶具を提供する。【解決手段】人の足を載せる足載せ台１と、足載せ台の足先側端部と足載せ台の踵側端部とを結ぶ中心線に直交する軸回りに回転するとともに、足載せ台の踵側端部の後方に配設した第１のローラ３と、軸回りに回転するとともに、足載せ台の中央部の下方に配設した第２のローラ４とを有し、第１のローラは、足先側端部から踵側端部に向かう方向の足載せ台の移動を拘束する一方、踵側端部から足先側端部に向かう方向の足載せ台の移動は許容するように一方向のみへの回転を可能に形成したものである。【選択図】図１
