PROBLEM TO BE SOLVED: To hold and press a nozzle head against a main body of a container with a cap under a simple configuration, further locate the nozzle head in a predetermined direction of the nozzle against the main body of the container and enable the nozzle head to be fixed. SOLUTION: A cap 12 and a nozzle head 13 in a capping device are rotated concurrently in a normal direction up to their final fastening position, then, the cap and the nozzle head are rotated concurrently in an opposite direction from the final fastening position by a loosening angleθ, and they are located at the loosening position, thereafter the nozzle head is displaced to be positioned at the displacement position before the nozzle head final position by the loosening angle amount and finally the cap and the nozzle head are rotated concurrently in a normal direction by the loosening angle amount.
