騒音化が望まれている。In the above prior art, the measures for damping vibration are insufficient, and the shape of the vibration isolating rubber does not make good use of the inherent vibration absorbing characteristics of the rubber, so that the electromagnetic force generated by a fan motor as a source is not sufficient. There was a lack of consideration for preventing vibration and abnormal noise generated from the motor base and the blower due to the propagation of vibration. Also, in recent years, as the size of the air conditioner has been reduced in recent years, the situation of housing has been overcrowded, and low vibration and low noise of the product have been desired.

And a bobbin shape having flanges at both ends so as to be less susceptible to vibration from the fan motor.

This is achieved by forming a state in which a compressive force is applied in a direction opposite to the center.

ゴムの構造を図２により説明する。[0009] The vibration isolating rubber has a function of preventing vibration noise generated when the blower rotates and electromagnetic vibration generated from the fan motor main body from propagating to the motor base. In the above-mentioned structure, as shown in FIG. 3, in the conventional vibration isolating rubber 7, the force generated by the own weight of the fan motor is always concentrated only at the point a, so that the inherent elastic characteristics of the rubber cannot be utilized well and the fan motor The structure is such that electromagnetic vibrations generated when the motor rotates are easily propagated from the motor base to the product body via the fixing bolts. Next, the structure of the anti-vibration rubber according to the present invention will be described with reference to FIG.

く、防振ゴム本来の働きを発揮できると考えられる。The anti-vibration rubber 6 having the elliptical collar forms a positional relationship in which the tip a 'of the elliptical collar is compressed by the fan motor main body by being attached to the fan motor. The anti-vibration rubber is supported at point b'c 'toward the anti-center direction of the fan motor by the reaction force of the received rubber. Due to the formation of the structure, the rubber elasticity inherent in the rubber portion A is always maintained,
It is thought that the electromagnetic vibration generated when the fan motor rotates can be easily absorbed, and the original function of the anti-vibration rubber can be exhibited.

Significant reduction is possible. Also, when fixing the fan motor, even if the fixing screw is fixed slightly off the center, the improvement of the vibration absorption performance of the anti-vibration rubber makes it easier to absorb the variation in workability than before,
