Abstract:
To provide a screw fastening method and device which can fasten a screw by a fastening force according to the output torque of a motor.
A screw is fastened by a bit 14 rotated by a motor 12, so as to fasten a fastened body. The screw is fastened by giving a vibration along the rotating direction of the motor 12, to a friction part existing in a space from the motor 12 to the fastened body through the bit 14 and the screw.
