底板２に伝わり難い。The anti-vibration rubber 1 attenuates most of the vibration transmitted from the compressor body 3 to the supporting plate 5 by first expanding and contracting the bellows portion 23 of the upper portion 7. Next, the constricted portion 16 between the thick portion 18 of the lower portion 6 and the maximum thick portion 13 expands and contracts to further damp the vibration. And the vibration damped in this way is
Since the vibration is transmitted to the bottom plate 2 only from the annular edge portion 11 of the lower end portion 8 of the lower portion 6 of the antivibration rubber 1, the attenuated vibration is difficult to be transmitted to the bottom plate 2.
