Beschreibung
Zusammenfassung:	The present invention is provided with a first drive unit that is connected to the input shaft of a test specimen and a second drive unit that is connected to the output shaft of the test specimen. The first and second drive units are provided with: a servo motor; a reduction gear that reduces and outputs the rotation of the output shaft of the servo motor; a chuck to which the input shaft or the output shaft of the test specimen is connected and that transmits the output of the reduction gear to the input shaft or the output shaft of the test specimen; a torque sensor that transmits the output of the reduction gear to the chuck and detects the torque that the reduction gear outputs; and a tachometer that detects the rotational frequency of the chuck.
