Claims

[Claims for Utility Model Registration] 1. A rotating shaft that is rotatably arranged to which force is applied from a person's arm or leg through an arm attached to one end, and a fixed shaft that has one end fixed. ,
a torque resistor that is interposed between the other end of the fixed shaft and the other end of the rotating shaft and applies a predetermined resistance force to the rotating shaft when the rotating shaft is rotated; a measuring means for measuring the amount of twist of the fixed shaft twisted through the torque resistor and calculating the torque applied from the arm based on the amount of twist of the fixed shaft. . 2. A rotating shaft rotatably disposed to which a force is applied from a person's arm or leg through an arm attached to one end, and a rotating shaft spaced apart from the other end of the rotating shaft. an intermediate shaft rotatably disposed on the same axis; and a torque interposed between the intermediate shaft and the other end of the rotating shaft to apply a predetermined resistance force to the rotating shaft when the rotating shaft is rotated. a resistor; a beam extending radially outward from the intermediate shaft and having its tip locked to restrict rotation of the intermediate shaft; and an intermediate member to which torque is transmitted via the resistor when the rotating shaft is rotated. A muscle strength measurement and training device comprising: measuring means for measuring the transmitted torque of the shaft via the beam, and calculating the torque applied from the arm based on the measured torque. 3. The muscle strength measurement and training device according to claim 1 or 2, characterized in that the rotation shaft is provided with a rotation means for forcibly rotating the rotation shaft.
