<p>A rotor balancing mechanism (1) has a rotor attaching member (4) and an adjusting mechanism (36). The rotor attaching member (4) has a rotary shaft portion (6) fixed to the rotary shaft (3) of a motor (2) that is a driver, and an elastic connecting portion (8) that elastically connects a rotor attaching portion (7) attaching and supporting a rotor (5) such as a disk in such a manner that the rotor attaching portion (7) is radially movable with respect to the rotary shaft portion (6). The adjusting mechanism (36) has an inside annular portion (27) directly or indirectly attached to the rotary shaft (3), an outside annular portion (28) directly or indirectly attached to the rotor attaching portion (7), and a plurality of rotary members (29) disposed between the inside and outside annular portions (27, 28) and capable of rotary motion on a circumference along the edge of either of the annular portions (27, 28). Further, one of the three parts, the inside annular portion (27), rotary member (29), and outside annular portion (28) is made of magnet, and one of the remainder is made of magnet or magnetic material.</p> |
