Lower surfaces of stepped portions of correction rings disposed at end plates (2) provided at both sides of a trunk (1) and erection portion rear surfaces of the end plates (2) are brought into contact with each other, and a control portion (10A) provided to a pressure unit (10) monitors a load torque of a motor, and presses butted parts through first pressing with a predetermined pressing force by controlling the position of a second correction jig (20B) and automatically performing fine adjustment of position movement of the second correction jig (20B). Thereafter, the control portion (10A) moves the correction rings to form spaces at an upper side, and presses the butted parts through second pressing with a predetermined pressing force by monitoring the load torque of the motor, and the trunk (1), the end plates (2), a first correction jig (20A), and the second correction jig (20B) integrally rotate.
