Achieved is a rubber bushing for railroad trucks which has a novel structure and is capable of improving, for example, flame resistance to externally applied fire or the like without greatly degrading the basic properties demanded with respect to vibrational and load inputs. A rubber bushing 10 to be used for railroad car trucks comprises a shaft-like inner member 12 and an outer member 14, disposed on the outer peripheral side of the inner member 12 at a remove therefrom, which are linked by a rubber elastic body 16. A cover part 48 that covers an exposed end surface 44, from the outside thereof, where the rubber elastic body 16 is exposed to the outside between the axial ends of the inner member 12 and the outer member 14, is provided at an axial end of the rubber elastic body 16 as a separate member from the rubber elastic body 16.
