PURPOSE:To absorb and attenuate the vibration of a compressor by forming resin-made vibration-proof material into a conical part in which the thickness is made gradually thinner from the bottom to the top so that soft elasticity can be provided by the vibration-proof material. CONSTITUTION:A vibration-proof member 1 comprises a compressor fitting part 1a at the top, a conical part 1b in which the rubber thickness is made gradually thinner from the bottom to the top, and a disk part 1c parallel to the bottom surface. As a result, even if soft elasticity is provided by the vibration-proof material 1, since the disk part 1c is hard to deform as compared with the conical part 1b, the contacted part becomes less when the vibration- proof member is compressed so that the movement required for the absorption or attenuation of vibration is hardly obstructed and the difference in elasticity between that at the free condition and that at the service condition is reduced. Further, since the shape of the vibration-proof member 1 becomes a jointed form at the service condition so as to be easily movable, vibration-proof effect can be obtained even for further large vibration. |
