狭い状態で成形しなければならない。By the way, in the vibration isolator 100, since the inner and outer cylinders 101 and 102 are molded in an eccentric arrangement, the main elastic portion 106 and the stopper portion 107 during the action of a static load. , 108, the gap width S1 of the void portion 105 on one side (for example, the rebound side) must be molded in a very narrow state.

が得られないといった難点があった。However, the thickness of the mold material for ensuring the voids during the vulcanization molding of the rubber-like elastic body is naturally limited in terms of its strength and durability. Therefore, there is a limit to the void width during vulcanization molding, and it is difficult to set the void width below that. Therefore, the minimum dimension S2 of the gap width (stopper clearance) during static load action is also limited, and the curve rising region at the time of stopper abutment cannot be set to a desired region in the load-deflection curve. However, there was a problem that the spring characteristics of the above could not be obtained.

By pressing the adjusting member having a thickness larger than the radial width thereof into the adjusting hole, the stopper portion is bulged toward the inner cylinder side, and the bulging portion reduces the gap width between the main elastic portion. By so doing, the stopper clearance can be adjusted when a static load is applied, so that a desired spring characteristic can be obtained.

法。5. A main elastic portion is formed around the inner cylinder by vulcanizing and molding a rubber-like elastic body in a state where a pair of voids are left between the inner and outer cylinders so as to substantially face each other with the inner cylinder interposed therebetween. Also, in the method of manufacturing a vibration isolator in which stopper portions facing the main elastic portion are respectively formed on the outer cylinder side of the void portion, in the stopper portion on the narrower gap width side, the adjustment hole is parallel to the axial direction of the inner cylinder. After vulcanization molding in the state of being formed in the above, after the vulcanization molding, an adjusting member having a thickness larger than the radial width thereof is press-fitted into the adjusting hole to bulge the stopper portion toward the inner cylinder side to obtain the main elasticity. A method for manufacturing an anti-vibration device, comprising reducing a gap width between the vibration isolator and the portion.
