Claims

[Claim for Utility Model Registration] A plurality of claws for gripping a workpiece are each formed with an extending arm, each arm is provided with a weight at its tip, and a straight line connecting the center of gravity of these weights and the center of gravity of the claw is the center of rotation. A rotating chuck mechanism characterized in that the centrifugal force of the weight cancels out the centrifugal force generated in the pawl during rotation.
