Zusammenfassung:	PROBLEM TO BE SOLVED: To lessen an abrasion damage due to rotation of a polygonal rod, thereby to improve durability and to correctly support the polygonal rod for a long period. SOLUTION: A rotor unit 10 is constituted of a plurality of rotor members 10a and 10b which can be divided and connected together and form a polygonal rod supporting hole 12 supporting the polygonal rod movably forward and backward, when they are connected together. The rotor unit 10 is supported rotatably by a divided type bearing 11.
