Abstract
A hydro bushing includes an outer pipe, an inner pipe disposed within the outer pipe and spaced apart from the outer pipe, an elastic body disposed between the outer pipe and the inner pipe and provided with a liquid chamber portion accommodating liquid therein, and a nozzle disposed between the outer pipe and the elastic body and including a stopper extending toward the liquid chamber portion such that a portion of an internal surface of the nozzle protrudes to be in contact with the liquid chamber portion. A contact end of the stopper is formed to have a surface corresponding to deformation of the elastic body caused by conical movement.
