PURPOSE:To provide a liquid seal type mount device having high damping effect for the vibrational input both from the axial direction and from the direction orthogonal to the axial direction by forming a thicker and a thinner parts of a rubber elastic body in the reverse relationship for the liquid chamber. CONSTITUTION:A plurality of liquid chambers 14 are separated from each other by a metallic piece 10 of the inner cylinder, a metallic piece 26 of the outer cylinder which is coaxially arranged to the inner cylinder, and a rubber elastic body 12 which is mounted between these cylinders in a stretching manner in this liquid seal type mount device, an incompressible liquid is filled in these liquid chambers 14, and at the same time, these liquid chambers are communicated with each other by means of an orifice passage 18. At one end part in the axial direction of the rubber elastic body 12, the side of the metallic piece 10 of the inner cylinder forms a thicker part 22 and the side of the metallic piece 20 of the outer cylinder forms a thinner part 24 toward one liquid chamber 14, while the side of the metallic piece 10 of the inner cylinder forms a thinner part 24 and the side of the metallic piece 26 of the outer cylinder forms a thicker part 22 toward the other liquid chamber 14. In addition, at the other end part in the axial direction, the thicker part 22 and the thinner part 24 of the rubber elastic body 12 are formed in the reverse relationship with the above- mentioned one for the respective liquid chambers 14. |
