PURPOSE:To provide a simple structure and facilitate the assembly by forming a hollow chamber in a part of a partition plate between a main liquid chamber and an auxiliary liquid chamber, using a hollow part wall face facing the auxiliary liquid chamber as a diaphragm wall, and forming a throttle passage connecting the main liquid chamber and the auxiliary liquid chamber together in the partition plate part excepting the hollow part. CONSTITUTION:A liquid sealed damper device is constituted in such a way as comprising a thick rubber wall 1, which supports a vibration body on the top face and is formed into a container-shape opening downward, a bottom plate 2, which is shaped into a container-shape opening upward and is connected with a base body at its bottom face while forms a sealed space by connecting its opening with the rubber wall 1 opening, and a partition plate 3, which devides the space in the bottom plate 2 into an upper part and a lower part so as to form a main liquid chamber A using the rubber wall 1 as its chamber wall in the upper part and an auxiliary liquid chamber B using the bottom plate 2 as its chamber wall in the lower part. A hollow part 31 is formed in a part of the partition plate 3, the hollow part 31 wall face facing the auxiliary liquid chamber B serves as a diaphragm wall 311, which is deformable according to the inner pressure of the auxiliary chamber B, and a throttle passage 32 connecting the main liquid chamber A and the auxiliary chamber B together is formed in the partition plate part excepting the hollow part 31. In this way, it is not necessary to make a rubber film separately, to keep it, and to assemble it. |
