Abstract
[Problem to be Solved] To provide an antivibration device that can realize low dynamic spring characteristics in a high vibration region while securing a damping force in a low vibration region. [Solution] In the case where a load input in the axial direction of a coupling member is a predetermined value or smaller, the dynamic spring constant of a first bushis set larger than that of a second bush, and the loss factor of the second bushis set larger than that of the first bush. On the other hand, in the case where the load input in the axial direction of the coupling memberexceeds the predetermined value, the dynamic spring constant of the first bushis set smaller than that of the second bush
