PROBLEM TO BE SOLVED: To provide a rotating body fixing structure at a low cost in which a fan 11 is not deviated in the axial direction of a rotary shaft 16 after the fan 11 and a cap 18 are press-fitted and fixed to the rotary shaft 16. SOLUTION: When the cap 18 is press-fitted and fixed to the rotary shaft 16 integrally with the fan 11, a rib fitting groove part 19 of the cap 18 is expanded in the radial direction of the rotary shaft 16, the bearing pressure is generated on inside and outside diameter part sides of a locking rib 17 of the fan 11, and the fan 11 is firmly fixed to the cap 18 by the bearing pressure. Therefore, the fan 11 is not deviated in the axial direction of the rotary shaft 16 of a motor 12. COPYRIGHT: (C)2004,JPO
