<P>PROBLEM TO BE SOLVED: To eliminate the need of the movement control of a transfer body. <P>SOLUTION: A holding portion 84 and a hook portion 86 are provided to the shaft portion 80A of a link member 80. The holding portion 84 and the hook portion 86 are provided to project from the outer circumferential surface of the shaft portion 80A, deviate (with a space) in the axial direction of the shaft portion 80A and have a predetermined angle difference with respect to the rotational axis of the shaft portion 80A. Thus, a releasing member 90 is caught on the hook portion 86, while the holding portion 84 comes into contact with the locking portion 72C of a bearing 72, to support the locking portion 72C. <P>COPYRIGHT: (C)2010,JPO&INPIT |
