ABSTRACT:
A workpiece is urged against a chuck by a press plate supported by one end of a piston rod through a ball bearing. A rear end of a cylinder for the piston rod is swingably supported by a ball interposed between the rear surface of the cylinder and a stationary plate. Bolts for securing the cylinder to the stationary plate are formed with tapered portions mating with the tapered openings of bushings fitted to the supporting plate so as to selectively permit swinging motion of the cylinder.
