Abstract
A vibration isolator includes a first metallic mounting member; a metallic body member disposed away from the first metallic mounting member in the vibration input direction; an elastic body portion elastically connecting the first metallic mounting member and the metallic body member; and a second metallic mounting member. The metallic body member includes a flange portion protruding radially outward from a part of its end facing the first metallic mounting member and a first protrusion protruding radially outward from the remaining part of the end to a greater extent than does the flange portion. The opposite end of the metallic body member is plugged with a seal member to thereby form a liquid chamber within the metallic body member. The second metallic mounting member is fixedly press-fitted onto the metallic body member and includes a second protrusion. The first and second protrusions are superposed to thereby form a stopper portion. The stopper portion is covered and held by a stopper covering portion.
