ABSTRACT:
Flanges are provided on a screw casing and a cylinder member of a screw driving unit in opposition to each other, and coupled with each other with fastening bolts. An adjusting ring is screwed onto the outer circumference of one of the flanges. The screw member is moved together with the ring in a backward direction until the end of the screw hits. The ring is rotated thereafter to bring it into contact with a side of the other flange, where a datum position is established. The cylinder member is then retreated an adequate amount in this state, and the ring is moved by a specified quantity. The specified quantity, represents the stroke quantity and bolts are fastened so that the ring comes into contact with the side of the other flange. The screw is thereby adjusted in its stroke.
