摘要： A tightening torque measuring unit capable of reducing errors with respect to either a clockwise or counterclockwise direction as soon as possible is provided. A tightening torque measuring unit 10, installed in a tightening device, includes a torque sensor 12 that detects a tightening torque and an amplifier that amplifies an output from the torque sensor 12. The amplifier 40 or 42 applies a different gain to the output from the torque sensor depending on whether the tightening direction of the tightening apparatus is clockwise or counterclockwise.

摘要： A controller compares a minimum value of power source voltage which decreases in association with starting current generated upon start of a motor with a threshold value in a storing unit. When the minimum value is less than the threshold value, the controller notifies of shortage of the power source terminal voltage, and stops the motor. The controller also compares a value obtained by integrating the power source voltage which decreases in association with starting current generated upon start of the motor for only predetermined time with the threshold value in the storing unit, when the integral value is less than the threshold value, notifies of shortage of the power source terminal voltage, and stops the motor.
