ABSTRACT:
An air chuck for use in a capping or uncapping machine, in which air chuck a plurality of hard members are circularly disposed and a cap receiving recess is formed in the central portion of the hard members. The hard members are so arranged as to be slid in the directions of the radii of the cap receiving recess and the sliding movement of the hard members enlarges or reduces the inner diameter of the cap receiving recess, the air chuck thereby grasping or releasing a bottle cap which is introduced into the cap receiving recess. The hard members are made of materials which are excellent in wear resistance and deterioration resistance, such as metals and synthetic resins, so as to be usable for a long period of time. The sliding movement of the hard members is effected by a driving member which is driven by compressed air.
