To provide a function similar to a torque rod, with a simple structure for less cost-increase, to a swing regulating mechanism 4 which is integrally provided to mounts 3 and 5 (antivibration mount) of a power plant P mounted horizontally on an automobile.
In the antivibration mount, a mount 3 on an engine side is provided with an inverted U-like stopper hardware 40 to stride over to and fro, a mount body 30. A stopper rubber 42 is formed to protrude toward a rear side leg 40c of the stopper hardware 40 from the rear end of a casing 31 of the mount body 30. A bore 43 is formed inside the stopper rubber 42 with a metal core 44 embedded for the core 44 to rotate around the lateral axis as a link. Thus, the stopper rubber 42 shear-deforms in the vertical direction with relative ease even under the compression force back and forth. The vertically moving spring of the mount 3 does not rise even if the stopper operates at abrupt acceleration or the like, sufficiently suppressing the acceleration booming sound of an automobile.
