An improved bearing structure has a plurality of spaced first ring members coaxially mounted on a stationary shaft, each of the first ring members having at its each radial side first means defining a first conical wall surface, a plurality of spaced second ring members coaxially mounted on the peripheral surface of a central bore of the rotary disc while alternatively projecting, in a meshing manner, into spaces defined between the first ring members, each of the second ring members having at its each radial side second means defining a second conical wall surface which is contiguously engaged with the first conical wall surface and holding means for providing tight connection between the first and second ring members and the stationary shaft. |
