Abstract
A guide rail is provided on an outer surface of a chuck body. A pair of fingers is disposed on the guide rail. At least one of the pair of fingers is a movable finger that is movable along the guide rail. One or two cylinder apparatuses, each of which has a rod that advances and retracts in the direction of its axial line by the action of air pressure, are provided in the chuck body. The top end of the rod extends from an end of the chuck body to the outside. An end block is attached to the top end of the rod. The end block is linked to the movable finger.
