PURPOSE:To make a pair of plates stickable fast without fail, and dispense with a positioning job in setting operation as well as to make manufacture so as to become so simple but accurate, by piercing a projection jutting out of one side of the paired plates through a hole of the other side plate. CONSTITUTION:A diaphragm 20, plates 22 and 24 and a support plate 26 are attached to a step part 18 of a base plate 12. A peripheral part of rubber 30 constituting a vibro-isolating main body is vulcanizedly stuck to the support plate 26, and a top plate 32 is vulcanizedly stuck to the inner circumferential part. At the time of vibrations in an engine to be mounted on this top plates 32, these vibrations are absorbable with resistance of internal friction of the rubber 30 is well as vibrations are absorbable with resistance when each fluid of an upper small fluid chamber 36A and a lower small fluid chamber 36B circulates through an orifice 40. In addition, at the time of high frequency vibration, even if the orifice 40 is loaded, it is absorbable with vibrations of a vibrator 52. |
