PROBLEM TO BE SOLVED: To prevent the occurrence of an unusual noise generated in an elastic partition and provide a non-linear spring characteristic even if a heavy vibration input of an engine occurs at starting and stopping of the engine. SOLUTION: A partition member 5 is composed of an elastic partition 20 and an outer peripheral supporting part 21. The elastic partition 20 has an outer peripheral ring 22, a taper part 24, a ring-shaped thick part 25 and a stopper leg 26. In the ring-shaped thick part 25, the stopper leg 26 which has a taper shaped section protruded in an outwardly opened state in the direction of the outer periphery, is integrally formed and abutted to the outer peripheral supporting part 21 and a pressing part 33. A stopper leg 26 is protruded to the side where the input ratio of a heavy vibration input of an engine is larger and deformed to such an extent as not to be separated from the pressing part 33 even if the heavy vibration input of an engine occurs, thereafter being pressed. |
