<p>PURPOSE:To surely regulate the respective phases irrespective of the number of columnar bodies by bringing the regulating surface of a pair of regulating members into contact with the respective circumferential surfaces of the columnar bodies, and regulating the position of the clearance between the respective columnar bodies relative to the body of revolution. CONSTITUTION:After one regulating member 30U of a pair of regulating members 30U, 30L is moved by a driving means 37U by the specified distance, and its tip part is inserted between columnar bodies, the other regulating member 30L is moved by the specified distance, and its tip part is inserted between the columnar bodies whereto the regulating member 30U is inserted. Then, the regulating surfaces 33U, 33L of these regulating members 30U, 30L are brought into contact with the respective circumferential surfaces of the columnar bodies. This arrangement regulates the position of the clearance between the columnar bodies relative to the body of revolution.</p> |
