An automatic tightening method comprises the steps of transferring a torque, generated in a driving section for a screw cap through a power transmission joint section to a container, thereby screw-tightening the screw cap in a tightening apparatus for screw-tightening the screw cap by a rotational torque from the driving section, detecting a tightening torque applied to the container, adjusting the driving section or the power transmission joint section when the tightening torque reaches a predetermined tightening torque, and holding the predetermined tightening torque for a predetermined period of time, thereby obtaining the predetermined tightening torque irrespective of the transmitted rotation torque. Also, an apparatus for carrying out the method is disclosed herein.
