としたことを特徴とする。SUMMARY OF THE INVENTION In view of the above, the present invention has been devised to solve the above-mentioned problems in the prior art, and in order to achieve this object, an inner ring and an outer ring are required. In a center bearing support in which the rings are connected via a bellows-shaped rubber-like elastic material spring member and the spring member is bonded to the inner peripheral surface of the outer ring, a non-bonded portion is formed between the spring member and the outer ring. And a fluid is sealed in the non-adhesion portion, and the spring member is swelled inward to form a radial stopper.

The non-adhesive portion is surrounded by an adhesive portion, and a fluid is sealed in the non-adhesive portion. When the fluid is sealed in the non-adhesive portion, the spring member expands toward the inner peripheral side, and when the fluid is stopped at a suitable place and sealed tightly, a radial stopper integral with the spring member can be formed. A fluid excellent in vibration absorbing power such as a viscous fluid is suitable for the fluid.

とによって減衰特性を調整することが可能である。As shown in FIG. 1, a metal outer ring 2 is disposed on the outer peripheral side of a metal inner ring 1, and a spring member made of a rubber-like elastic material in which the inner ring 1 and the outer ring 2 have a bellows shape. 3 are connected. The spring member 3 is annular. The spring member 3 is bonded to the inner peripheral surface of the outer ring 2. The outer ring 2 and the spring member 3 are partially provided with an annular non-adhesive portion 4, and further, annular non-adhesive portions 5 and 6 are provided on both sides of the non-adhesive portion 4 in the axial direction. The fluid 8 is sealed in the non-adhesion part 4 from the injection hole 7. Non-adhesion is due to not applying an adhesive. When the fluid 8 is sealed in the non-adhesive portion 4, the spring member 3 expands toward the inner peripheral side. When a predetermined amount of the fluid 8 is injected, the injection is stopped and the injection hole 7 is closed with the ball stopper 9. As a result, the radial stopper 10 integrated with the spring member 3 can be formed, so that the number of steps required for manufacturing can be reduced and the manufacturing cost can be reduced as compared with the related art. Further, the attenuation characteristic can be adjusted by increasing or decreasing the injection amount of the fluid 8.
