Patent ID: 7032701

Claim:
A supporting structure of a vehicle power source comprising: a plurality of mount members having elasticity through which a power source is elastically mounted on a vehicle body, said power source comprises an engine and a transmission; first mount members for primarily sharing the weight of the power source and at least one of the first mount members, which is supported by said vehicle body at a first height lower than the height of a gravity center of said power source, is attached to a sub-frame; and second mount members for secondarily sharing the weight of the power source and the second mount members, which have a spring effect in at least one of longitudinal and lateral directions of said vehicle body, are attached to the vehicle body at a second height higher than the gravity center of said power source, said first members comprising a front mount disposed at a front side of said engine and a rear mount disposed at a back side of the engine, said second members comprising a side engine mount disposed at an end opposite to said transmission and a trans-upper mount disposed on the transmission; wherein the height of a center of elasticity of the supporting structure, defined by the first and second mount members, is set to be higher than the gravity center of said power source.
