PURPOSE:To enable to obtain the maximum static friction torque and a dynamic friction torque simultaneously with a repeated measurement by providing a computation means of computing the lowest value and the minimum value of torque appearing during the measurement. CONSTITUTION:A control signal is applied to a rotation driver 4 with a controller 11 to start the driving and a control signal is applied to a torque sensor 6 to start the measurement. The torque value measured with the torque sensor 6 is brought into an arithmetic unit 31 at each fixed cycle and the minimum value and the maximum value obtained during one measurement are stored into a memory 32. An arithmetic unit 33 calculates the maximum static friction torque and a dynamic friction torque bases on the value stored in the memory 32. |
