A torque rod having an arm portion, a ring portion formed on each end of the arm portion in a longitudinal direction of the arm portion, and a rubber bushing that is integrally provided with the ring portion. The arm portion is formed from a material that is lower in specific gravity than iron. A weight is provided in a potion of the rubber bushing other than a principal spring portion. The principle spring portion, which absorbs principle vibration to be isolated, is formed by an elastic arm portion that extends radially outwardly from an inner cylinder located substantially in a center of the rubber bushing and is connected to the ring portion. An aperture, which is a separation space, is provided between the elastic arm portion and the ring portion.
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:
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 having an outer periphery that is connected to an inside surface of said ring portion and defining forward and backward apertures, said forward and backward apertures extending through said bushing comprising forward and backward stopper portions and first and second elastic arm portions, wherein said forward aperture separates said forward stopper portion from said elastic arm portions, said backward aperture separates said backward stopper portion from said elastic arm portions, and wherein a weight is fitted into a concave portion recessed in an inward direction of said inner peripheral wall of said ring portion such that said weight is located outside of a restraint line of said rubber bushing by said ring portion.
