Vibration isolating device

摘要

A vibration isolator wherein an inner and an outer cylindrical fittings are connected by a rubber elastomer between both fittings; in the rubber elastomer above and below the inner cylindrical fitting, hollow spaces are formed circumferentially in a larger width, in a cross-section square to the axial direction, than an outside diameter of the inner cylindrical fitting, and lateral portions as support arms of the rubber elastomer between the hollow spaces support the inner cylindrical fitting to the outer cylindrical fitting. In order to lower the dynamic spring rate in the lateral direction square to the axial direction and facilitate the tuning of rigidity, without changing the vibration-isolating characteristics in the vertical direction and without deteriorating the durability, it is characterized in that small vacancies are provided in the lateral portions at a distant position inboard from the outer cylindrical fitting. <IMAGE>
