Abstract
A screwing machine includes a motor, an output shaft, a twist portion, a plate portion, a strain gauge, an amplification circuit. The output shaft is driven by the motor. To the output shaft, a bit is attachable. The twist portion is hollow. To the twist portion, torque applied to the output shaft is transmitted through a transmission element. The output shaft is configured to be indirectly twisted by the torque applied to the output shaft. The plate portion is integrally formed with the twist portion. The strain gauge is disposed on the twist portion. The amplification circuit is disposed on the plate portion. To the amplification circuit, a signal from the strain gauge is input.
