A shaft bearing structure comprises a shaft which is to be rotatably supported, a bushing disposed on the shaft, the bushing having an outer surface tapered in an axial direction so as to have a frusto-conical configuration, a support member having a support opening for receiving the bushing, the support opening having an inner surface tapered in an axial direction so as to have a frusto-conical configuration, and a biasing member on the shaft biasingly urging the bushing in an axial direction such that the tapered outer surface of the bushing is biased into mating contact with the tapered inner surface of the support opening. |
