Abstract: A capping machine includes a gripper having a pair of gripping arms provided on an outer peripheral portion of a rotating body and configured to grip a cylindrical portion of a vessel, an opening and closing device configured to open and close the gripping arms, and a capping head liftably and rotatably provided on the rotating body. The gripping arms are arranged symmetrically with respect to a radius of the rotating body. The gripper has a protrusion for preventing the vessel from rotating on a vessel gripping surface of the gripping arms. The gripping arms have outer and inner gripping surfaces which are connected in a V shape. The protrusion is formed only on the inner gripping surface of a right gripping arm. A cap held by the capping head is screwed onto the vessel while sticking the protrusion into the cylindrical portion.
