Antivibration device

An antivibration device comprising a main body fitting having a cylindrical drum part, an upper attachment fitting adapted to be connected to a vibration generator side, a vibration-isolating base made of rubber-like elastomer interconnecting an upper opening of the main body fitting and the upper attachment fitting, a stopper fitting coupled to the main body fitting, the stopper fitting assuming a generally cylinder form with a partly cutout portion and extending upwardly outboard of the vibration-isolating base, the stopper fitting being at its upper end part bent inwardly as a stopper portion performing a stopper action against a large vertical displacement of the upper attachment fitting,

• which device is characterized in that the stopper fitting is fitted with a stopper rubber member by vulcanization molding, the stopper rubber member extending from a top surface of the stopper portion to an outer surface of a side plate of the stopper portion, and
• a heat shield rubber membrane portion plugging the cutout portion of the stopper fitting is formed by vulcanization integrally with the stopper rubber member.
