摘要： A fluid -filled elastic bushing wherein an elastic body elastically connecting a center shaft member and an outer cylindrical member is provided a displacement restrictor including a stop portion extending from one of the center shaft and outer cylindrical members toward the other member, to restrict an amount of radial displacement of these two members. The stop portion includes an abutting part opposed to the other member with a first radial spacing therebetween, and a shoulder surface adjacent to the abutting part. The displacement restrictor further includes a buffer layer disposed in close contact with the shoulder surface and made of an elastic material whose stiffness is lower than a material of the abutting part. The buffer layer is opposed to the above-indicated other member with a second radial spacing therebetween smaller than the first radial spacing.
