Patent ID: 8684341

Claim:
A torque rod comprising an arm portion being formed of a material which is lower in specific gravity than iron, a ring portion being formed on each end in a longitudinal direction of said arm portion, and a rubber bushing being integrally provided with each of said ring portions, at least one of said rubber bushings comprising: an elastic arm portion connecting an inner cylinder located substantially in a center of said at least one of said rubber bushings with said ring portion, said elastic arm portion forming a principal spring portion, a forward aperture and a backward aperture, which are separation spaces, being provided between said elastic arm portion and said ring portion, and a forward stopper portion and a backward stopper portion being separated from said elastic arm portion by said forward aperture and said backward aperture and being integrally provided with said ring portion, and wherein a weight is integrally provided within at least one of said forward and backward stopper portions or within a rubber in a vicinity of at least one of each end in right and left directions of the forward aperture and/or the backward aperture of said rubber bushing, said weight being disposed within said at least one of said forward and backward stopper portions or said rubber so as to be radially inwardly of said ring portion toward said inner cylinder, whereby a mass of the weight is selected so that a resonance of the torque rod falls within a predetermined resonance range to be vibration-isolated.
