PROBLEM TO BE SOLVED: To detect forces applied to left and right feet during exercise, and to make a user recognize the way of forces to be applied to the left and right and conscious to perform an exercise without left-and-right imbalance.SOLUTION: A passive exercise device includes a pair of footrests 211, 212 on which the left and right feet are placed, respectively, and which passively exercises the user by displacing the pair of footrests 211, 212 with a drive means 30 comprising a drive source. Each of the footrests 211, 212 has a force detection means 511, 512 for detecting the force applied to each of the footrests, respectively. A force evaluation amount is found by an evaluation means 52 from the force detected by the force detection means 511, 512 and the found force evaluation amount is displayed by a display means 53.COPYRIGHT: (C)2012,JPO&INPIT【課題】運動中に左右の足に作用する力を検出するとともに、使用者に左右の力のかかり方を認識させて左右の偏りのない運動を行うように意識付ける。【解決手段】他動運動機器は、左右の足をそれぞれ載せる一対の足置台211、212を備え、駆動源を備えた駆動手段30で各足置台211,212を変位させることにより、使用者に他動的に運動を行わせる。各足置台211,212は、それぞれ足置台211,212に作用する力をそれぞれ検出する力検出手段511,512を備える。力検出手段511,512が検出した力から評価手段52において力評価量が求められ、求められた力評価量は表示手段53に表示される。【選択図】図1
