PROBLEM TO BE SOLVED: To provide a device capable of preventing aging by applying an artificial impact similar to walking and running to bones for a bed-ridden person.SOLUTION: A sandal 1 is mounted on a foot part. An intermittent current is caused to flow to an electromagnet 4 from an external power source through a control circuit part 10 and a variable resistor 11 with a switch so that an impact similar to walking and running is applied to bones from the sole.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2020,JPO&INPIT【課題】寝たきりの人のために歩行、ランニングと同程度の衝撃を人工的に骨に加えることにより老化防止を行うことが出来る装置を提供する。【解決手段】サンダル1を足部に装着し、外部電源から制御回路部10及びスイッチ付き可変抵抗器11を介して電磁石4に間欠電流を流し、歩行、ランニングと同程度の衝撃を足裏から骨に加える。【選択図】図4
