PROBLEM TO BE SOLVED: To facilitate the connecting work of a fluid passage and to broaden the damping characteristics, when a fluid passage joined at a joining part of each circular arc-like member is provided, in a liquid-sealed vibration control device, in which a pair of circular arc-like grooves separated with an elastic partitioning wall is covered with a ring member. SOLUTION: A pair of circular arc-like grooves 4, 5 are provided on the outer peripheral part of an elastic vibration control member interposed between an outer cylinder 1 and an inner member 2 arranged concentrically. Both grooves 4, 5 are separated with elastic partitioning walls 6, 7 extending in the opposite directions, with the inner member 2 between them, and respective circular arc-like grooves 4, 5 are fitted to circular arc-like members 8, 9. The circular arc-like members 8, 9 form a continuous ring shape by joining adjacent connecting surfaces 12, 13. At the joint-end part in the vicinity of this joining part, a large fluid passage 14 and a small fluid passage 15 are formed, and the fluid passages 14, 15 are communicated at the joining part of the connecting surfaces 12, 13, in a large passage and small passage state.
