The invention aims to provide a torque rod which, by adding an improved rod portion, has not only compression and tensile strength, but also increased bending and twisting stiffness. By the present invention, the twisting stiffness can be raised to 2 to 3 times that of a conventional rib shape. A torque rod, the torque rod structure comprising a rod portion with a built-in pair of rubber bushes, which are formed respectively around a pair of cylinders, the rod portion linking both the rubber bushes, wherein the cross-sectional shape of the central portion of the rod portion forms a rectangular shape and one pair of opposing edges of the rectangular shape form a shape which bulges outwards, and the cross section of the rod portion is one of a hollow portion, honey comb shape, or rib structure. 11, 12 . . . internal cylinders, 20 torque rod, 21 . . . hollow portion.
