The bearing movable portion 11 is arranged so that the shape of the gap is narrowed and a wedge is formed. In the case of this modified example, it is expected that the movement of the bearing movable portion 11 can significantly change the end shape 7 of the dam-shaped groove 4 and the gap shape of the dam-shaped groove 4. The same effect can be obtained even if the entire upper bearing is movable, and the control circuit can be operated during operation to control the eccentricity (rate) of the upper bearing with respect to the rotating shaft. Needless to say.
