    • A rotary apparatus comprises a non-rotary part (14,34,54), a rotary shaft (12,32,52) rotatable relative to the non-rotary part, a rotary member (16,36,56) provided between the rotary shaft and the non-rotary part, an inside bearing (18,38,58) provided between the rotary shaft and the rotary member, and an outside bearing (20,40,60) provided between the rotary member and the non-rotary part. The inside bearing comprises a first inside bearing (18a,38a,58a) and a second inside bearing (18b,38b,58b) which are spaced to each other along a direction (X) of a central axis of the rotary shaft. The outside bearing comprises a first outside bearing (20a,40a,60a) and a second outside bearing (20b,40b,60b) which are spaced each other along the direction (X) of the central axis of the rotary shaft. An outer ring of the first inside bearing and an inner ring of the first outside bearing are fixed on the rotary member. An outer ring of the second inside bearing and an inner ring of the second outside bearing are fixed on the rotary member. In a condition in which an inner ring of the first inside bearing and an inner ring of the second inside bearing are fixed on the rotary shaft, if an outer ring of the first outside bearing and/or an outer ring of the second outside bearing are/is being fixed on the non-rotary part, then the outer ring of the first outside bearing and/or the outer ring of the second outside bearing move/moves along the direction of the central axis of the rotary shaft. Due to interlocking of them, the rotary member slightly moves along the direction of the central axis, whereby at least two of the first inside bearing, the first outside bearing, the second inside bearing, and the second outside bearing receive respective preloads with a linkage relationship.
