SOLUTION: A fixed-side magnet 37 and a rotary-side magnet 39 are placed so as not to attract each other, and rotary driving means 50, 48, 48a, and 44 are rotated and drived so that a member 23 to be positioned can be dislocated in its rotary direction and the fixed-side magnet 37 and rotary-side magnet 39 face each other and attract each other. Further, a ball member 36 is engaged with a groove 28a so that the member 23 to be positioned can be positioned at the specified position of its rotary direction and fixed thereat. Therefore, the change of position of rotary direction in the member 23 to be positioned or its positioning work can be automated. |
