PROBLEM TO BE SOLVED: To provide a capping work, secured and stabilized, not affected by the inertia force generated by a capping head, etc., by forming a simple control structure used even for a screw cap of small total screwing-in angle formed all over from the setting time of a cap to the joining time for joining the bottom of the cap with the upper end of a container mouth like a screw cap such as an eye lotion container. SOLUTION: The height position of a capping head 10 is sensed by a sensing means 3 in the capping work, and when the height position of the capping head 10 conforms to a preset given height before the bottom of the cap 11 is joined with the upper end of the mouth of a container 12, the rotating speed of a servo motor 2 is controlled and reduced, and also the control to a given clamping torque is provided by the control work.
