摘要： The present invention aims to provide a screw fastening machine for reliably switching and changing a driving force transmitting path with the seating on a work as a reference.According to the screw fastening machine in which a first pulley is connected to a first driving means for applying high speed low torque drive to a drive shaft, a second pulley is fixed in an integrally rotatable manner to a transmission shaft for connecting the drive shaft, and an endless belt is interposed between the pulleys to obtain a configuration for high speed low torque drive, a second driving means for low speed high torque drive is arranged on an extension of the transmission shaft, and the second driving means performs the drive until a final fastening torque is reached when a screw component is seated on the work and the stall state is achieved, the final fastening torque is always reliably obtained and the work time is reduced without waste. Since the second driving means for low speed high torque is not rotatably driven while the first driving means for high speed low torque is being driven, the power is not wasted and energy-saving effect that fits with the times is obtained.
