PROBLEM TO BE SOLVED: To easily and surely connect tip end parts of circular arc-like members and to broaden the damping characteristics, in a liquid-sealed vibration control device, in which a pair of circular arc-like grooves separated with an elastic partitioning wall are covered with a ring member. SOLUTION: A pair of circular arc-like grooves 4, 5 are formed on the outer peripheral part of an elastic vibration control member 3 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. Adjacent end parts of the circular arc-like member 8, 9 are formed into step-like end parts 12, 13, and both 8, 9 are formed into one continuous ring member, by superposing and joining outside and inside in the radial direction. A small fluid passage 15 is formed within a thickness of the step-like end part 13 on one side, and one end of the passage 15 is communicated/connected with a large fluid passage 14 consisting of the groove formed on the step-like end part 12 on the other side. |
