PROBLEM TO BE SOLVED: To provide a liquid-sealed type vibration isolating support device suitable for an engine mount A etc. capable of easing impact when a movable plate 42 is abutted to a wall surface of a storage chamber R formed in an orifice board 4 partitioning a liquid chamber F, capable of decreasing transmission force to a vehicle body side, and capable of reducing a noise in a cabin. SOLUTION: A first projection 42a orbiting an outer periphery is formed on both surfaces of the movable plate 42, and second and third projections 42c and a hemispherical protrusion 42d are formed near the inner periphery. A protrusion height of the first projection 42a is a little low, and the projections 42c and the protrusion 42d are abutted to the wall surface first, and the impact is eased.
