Although it is conceivable to increase the hardness to increase the strength, this measure can reduce the damage of the rubber, but the increase in the rubber hardness lowers the vibration isolation effect. Therefore, the vibration generated by the compressor is transmitted to the fixed base 4 side, which causes an increase in vibration and noise in the compressor installation space. The present invention has been made in view of the above points, and an object of the present invention is to provide a vibration-damping support structure for a compressor in which damage of the vibration-proof rubber is less likely to occur while ensuring the vibration-proof effect of the vibration-proof rubber.

変形により防振作用を果たすことができる。The mounting leg 12 of the compressor 10 is elastically supported and fixed to the vehicle body 18 side via the vibration-proof rubbers 13 and 14 compressed by a predetermined amount by tightening the bolt 16. The stopper plate 19 is a sleeve 15
It is fixed in a state of being sandwiched between the lower end of the vehicle body 18 and the vehicle body 18. Next, the operation of the vibration-proof support structure of the compressor 10 assembled as described above will be described. Vertical vibration (upward displacement of the compressor 10)
Can be absorbed by the compressive deformation of the upper anti-vibration rubber 13, and downward vibration (displacement of the compressor 10 in the downward direction) can be absorbed by the compressive deformation of the lower anti-vibration rubber 14. With respect to the above vibration, the vibration damping effect can be achieved by the compression deformation of the vibration damping rubber 13 or 14.

い。On the other hand, even in the case of horizontal vibration, the circular protrusions 13c and 14c of the anti-vibration rubbers 13 and 14 fitted in the circular seats 12b and 12c of the mounting leg 12 are provided between the mounting leg 12 and the sleeve 15. By being compressed, a vibration damping effect can be achieved. In this way, the vibration damping effect can be achieved by the compression deformation of the vibration damping rubbers 13 and 14 against both vertical and horizontal vibrations, and the tensile force as in the conventional structure can be obtained. 14 does not work.

Anti-vibration rubber 13, 1 even when an exciting force is applied
The strength of No. 4 does not occur and the strength can be secured.
