ABSTRACT:
There is provided a vibration damping device including; a pair of rubber arm portions connecting an inner fitting and an outer fitting to each other in the horizontal direction; and a rubber leg portion connecting in the vertical direction; the paired rubber arm portions are formed so that the thickness thereof decreases gradually from the inner fitting side toward the outer fitting side, and the rubber leg portion is formed so that each of both side surfaces is formed by an inwardly depressed curved surface, and is formed into a curved broaden shape toward the outer fitting side. Thereby, a spring constant in the horizontal direction is increased advantageously while a spring constant in the vertical direction kept large, and the durability of the rubber elastic body can be increased effectively.
