Hydro bushing

A hydro bushing comprising:

• 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,
• wherein a surface of a contact end of the stopper has a circumferential shape formed in a circumferential direction of the inner pipe, and
• the circumferential shape has the same circumferential curvature as an outer radius of the inner pipe,
• a gap in a load direction is present between the nozzle and the elastic body, and
• the circumferential shape of the surface of the contact end is formed based on a movement of a virtual circle by the gap with respect to a center point of the inner pipe, a radius of the virtual circle corresponds to an outer radius of the inner pipe.
