PURPOSE:To control the various input vibration effectively by providing an elastic bush, which can tune the damping characteristic in a wide range, as an elastic bush, in which an inner cylinder and an outer cylinder are connected by an elastic body and which has a damping mechanism for generating the damping force with deformation of the elastic body, especially as an elastic bush, in which an inner cylinder and an outer cylinder are relatively displaced in the axial direction at the time of transmitting the vibration to control the vibration. CONSTITUTION:A damping mechanism consists of a liquid chamber 22, of which volume is changed by the deformation of rubbers 18, 19 for connecting concentrically arranged an inner cylinder 14 and an outer cylinder 15 to each other, with the relative displacement of the inner and the outer cylinders in the axial direction, and an orifice 24. A damping mechanism consists of each liquid chambers 25, 26, of which volume is changed by the deformation of the rubbers 18, 19, and an orifice 27. These damping mechanisms are arranged in series between the inner cylinder 14 and the outer cylinder 15. |
