Abstract: 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.

Abstract: A synthetic resin rack guide in a rack-and-pinion type steering gear is provided with a projection formed on an outer peripheral surface at an end portion which is in contact with a rack bar. The projection is designed in such a manner that a diameter thereof after shrinkage due to annealing is equal to or slightly larger than an inner diameter of a guide hole for receiving the rack guide. With this arrangement, an abnormal noise created between rack teeth and a pinion may be prevented.
