Abstract
A set of bolt holes through which bolts are inserted are formed in left and right sides of a large end section. The bolt holes are substantially parallel to the axis of a rod section and are located such that the centers of the bolt holes are each displaced from the center of a cut surface. When a first mandrel and a second mandrel are press fitted to a joint hole of the large end section and are cut and split, the area of contact of the second mandrel on the movable stage side with the inner wall of the joint hole is set greater than the area of contact of the first mandrel on the fixed stage side with the inner wall of the joint hole.
