Abrégé

In a guide bush adjusting device, a drawbar (24) (a mobile body) provided to be displaceable with respect to a guide bush sleeve (7) is formed from: a screw connection member (14) (a connection member) which is connected to a guide bush (9) housed in a guide bush sleeve (7) (a cylindrical body); and an operation member (18) configured to operate the displacement of the screw connection member (14). The guide bush adjusting device adjusts an inner diameter dimension of the guide bush (9) by: releasing the operation member (18) from its fixation, displacing the drawbar (24), and fixing the operation member (18) at a predetermined position; and moving the guide bush (9) with respect to the guide bush sleeve (7), and positioning the guide bush (9).
