According to the conventional vibration isolator for the fan motor, the anti-vibration rubber 56 is interposed between the motor mounting plate 53 and the annular portion 54 of the fan case 55. The resonance between the motor shaft 57 and the fan 51 and the vibration generated from the motor 52 cannot be mitigated, and there is a problem that the vibration isolation device for the fan motor cannot be satisfied. Further, when the fan motor is driven at a low speed, low frequency vibration is generated. The hardness of the anti-vibration rubber 56 needs to be made extremely low in order to reliably prevent this low-frequency vibration, but if the hardness is made low, the anti-vibration rubber cannot be made flame-retardant. There is a problem that it cannot be used as a vibration isolator or that low frequency vibration cannot be damped.
