PROBLEM TO BE SOLVED: To provide an operation assisting apparatus capable of independently and safely assisting the recovery training or the like of a patient.SOLUTION: When an operation of walking of the patient is assisted, a DC motor 50 mounted on the knee joint part of the leg of the patient and assisting the bending operation and the extension operation of the knee joint part accompanied with the walking, is used. During a first period during the extension operation following the bending operation, the DC motor 50 is driven by a first driving force to assist the extension operation, and after the first period passes, during a second period before starting the next bending operation, the DC motor 50 is driven by a second driving force smaller than the first driving force to assist the extension operation.COPYRIGHT: (C)2012,JPO&INPIT【課題】患者の回復訓練等における補助を自立的且つ安全に行うことが可能な動作補助装置を提供する。【解決手段】患者の歩行の動作を補助する場合に、患者の脚の膝関節部に装着されており、歩行に伴う膝関節部の屈曲動作及び伸展動作を補助するDCモータ50と、屈曲動作に続く伸展動作中の第一の期間においては第一の駆動力によりDCモータ50を駆動させて伸展動作を補助させ、第一の期間経過後且つ次の屈曲動作が開始される前の第二の期間においては、第一の駆動力より小さい第二の駆動力によりDCモータ50を駆動させて伸展動作を補助させる。【選択図】図3
