<P>PROBLEM TO BE SOLVED: To provide a rotating body in which a disc member can easily be fixed to a shaft member. <P>SOLUTION: A rotating body comprises a rotating shaft 26 and a thrust disc 29. The rotating shaft 26 axially extends and is rotatable. The thrust disc 29 is fixed to the rotating shaft 26, and its position in the axial direction is held together with the rotating shaft 26 by receiving a magnetic force of a thrust magnetic bearing 28. Furthermore, the thrust disc 29 is divided into a plurality of divided parts in the circumferential direction. The thrust disc 29 is fixed to the rotating shaft 26 by an effect that the plurality of divided parts are fixed to the rotating shaft 26 with bolts, or an effect that the divided parts which are adjacent to each other in the circumferential direction out of the plurality of divided parts are connected to each other with bolts. <P>COPYRIGHT: (C)2013,JPO&INPIT |
