ABSTRACT:
A vibration isolating apparatus is provided which can reduce the manufacturing costs thereof. A space defined by an elastic body and a partitioning member28forms a main liquid chamber30. A non-return valve34is provided which allows flow-in of liquid only from the main liquid chamber30side via a pass-through hole24A of an upper member24forming the upper portion of the partitioning member28. A plunger36is disposed within an annular rib24B of the upper member24so as to be fit with the inner wall surface of the annular rib24B in a slidable manner. A coil spring38for urging the plunger36upward is disposed between the plunger36and the bottom surface central portion of a lower member26forming the lower portion of the partitioning member28.
