PURPOSE:To enable damping action of axial direction by providing two fluid chambers in the axial direction by separating member with orifice between an inner cylinder member and an outer cylinder member. CONSTITUTION:Fluid chamber 56, 58 are sectioned by a thin rubber layer 32, a relatively thick circular rubber elastic body 30 on one end side and a thin circular rubber elastic body 30 on the other end side between an inside metal fitting 10 which is an inner cylinder member and an outside metal fitting 26 concentrical thereto. A sectioning member 46 provided with a communicating passage 62 as an orifice means is provided between the inside metal fitting 10 and the outside metal fitting 26 to form two fluid chambers 56, 58 in the axial direction by the member 46, and damping action in the axial direction can be obtained. |
