Abstract
A mounting apparatus for a power unit comprises a first elastic member comprising a rubber-like elastic member and a second elastic member comprising rubber-like elastic members and a mass member therebetween. The first and second elastic members are disposed in parallel, wherein the weight of mass member can be changed or the second elastic member can be functionally engaged and disengaged with the first elastic member so that the reduction of the spring constant or oscillation transmitting rate is obtained just above the resonant frequency of the second elastic member while the degrading of the oscillation transmitting can be prevented below the resonant frequency.
