Vibration isolating device

Vibration-isolating device comprising:

• an inner cylindrical fitting,
• an outer cylindrical fitting disposed outwards to surround the inner cylindrical fitting,
• a rubber elastomer interposed between and connecting the inner and outer cylindrical fittings,
• the rubber elastomer being adjacent the entire inner surface of the outer cylinder,
• the rubber elastomer having therein circumferentially upper and lower hollow spaces defined above and below the inner cylindrical fitting,
• the upper and lower hollow spaces having a width, in a cross-section square to the axial direction, larger than an outside diameter of the inner cylindrical fitting,
• the hollow spaces being defined at their entire circumferences by the rubber elastomer,
• the rubber elastomer which extends between the upper and lower hollow spaces constituting lateral portions,
• the lateral portions of the rubber elastomer supporting the inner cylindrical fitting to the outer cylindrical fitting,
• the rubber elastomer consisting entirely of a rubber elastomer material without including metallic members or other members of different material from the rubber elastomer, and
• the rubber elastomer extending from a first point proximate a first end of the inner cylinder to a second point proximate a second end of the inner cylinder, and surrounding and contacting an entire outer surface of said inner cylinder between the first point and the second point,
• wherein particular portions of the rubber elastomer that are opposed to the lateral portions via the hollow spaces constitute stoppers and the lateral portions of the rubber elastomer have small vacancies defined at a distant position inboard from the outer cylindrical fitting.
