Claims

[Scope of utility model registration request]

A motor, a torque converter connected to the drive shaft of the motor to convert the torque of the motor, and a torque converter connected to the output shaft of the torque converter so as to be integrally rotatable, and fitted into a screw tightening member to convert the torque of the motor. In a screw tightening machine equipped with a wrench for rotating a tightening member, a spring is disposed between a main body connected to an output shaft of the torque converter and a torque plate connected to the wrench. A clutch that allows the output shaft of the torque converter and the wrench to rotate relative to each other and controls and transmits rotation of the output shaft of the torque converter to the wrench is provided between the torque converter and the wrench. A screw tightening machine characterized by being interposed between.
