CONSTITUTION:A mount insulator 1 includes an inner sleeve 2 and an outer sleeve 3 which are coaxially arranged, and both the sleeves are connected with each other by a main elastic member 4 made of rubber. The main elastic member 4 extends in a lateral direction of a vehicle, and is provided with intermediate plates 6 therein. A pair of massive members 8 and 8a are mounted through sub elastic members 7 and 7a to opposite inner surfaces of the outer sleeve 3 by utilizing spaces 5 and 5a in such a manner as to be arranged symmetrically with respect to the inner sleeve 2. When bivration of the outer sleeve 3 is transmitted to the massive members 8 and 8a, a pha of the vibration in a specific frequency area is delayed by 180 deg. to result in a reverd pha, thereby canceling the vibration of the outer sleeve 3 and reducing vibration transmitted to the inner sleeve 2.
