摘要： PROBLEM TO BE SOLVED: To positively grip a deformed workpiece with simple work without changing a jaw (a mouthpiece) mounted to a jaw of a stock vice regarding an attachment used in holding the deformed workpiece with the stock vice. SOLUTION: This attachment provided with two opposed soft jaws is inserted between jaws to grip the workpeice. Two soft jaws are energized in the separating directions from each other by built-in compression spring elements 7 and provided with stopper elements for locking the clearance. The basic shape of the soft jaw is a rectangular solid, and a recess corresponding to the outline of the workpiece is machined for use. The side face of the soft jaw is provided with a dislocation preventing element projected onto the back face side. A reference dislocation preventing element and an opposed movable dislocation preventing element are provided as the dislocation preventing element to accurately determine the machining reference of the workpiece.
