Although the fan 9 is rotated by the electric motor 4, deviation of the center of gravity occurs at this time due to manufacturing variations, and vibrations that are eccentric in the rotation direction of the electric motor 4 and vibrations due to magnetism due to the characteristics of the electric motor 4 are generated. An anti-vibration rubber 7 which is an elastic body is inserted between the electric motor 4 and the air conditioner body 3 so as to prevent this vibration from being transmitted to the air conditioner body 3, and the vibration of the air conditioner body 3 is measured. At this time, in order to keep the rotation center of the electric motor 4 at a fixed position, the fixed shaft 6 and the antivibration rubber 7 are in close contact with each other on the entire surface, and the mounting plate 5 of the electric motor and the antivibration rubber 7 are also in close contact. or,
When a load is applied to the mounting plate 5 of the electric motor 4, the anti-vibration rubber 7 absorbs vibration by changing the shape between the mounting plate 5 of the electric motor 4 and the stopper plate outwardly.
