    Abstract: A bearing device supporting a rotation shaft of a fuel cell compressor includes a pair of radial foil bearings and mounted in concentric relation to the rotation shaft and supporting the rotation shaft in a radial direction, and an axial magnetic bearing opposed to the rotation shaft in an axial direction and supporting the rotation shaft in the axial direction. A control device includes bearing life diagnostic unit for accumulating times during which a rotational speed of the rotation shaft has been below a predetermined value, so as to obtain a cumulative contact time, thereby judging a bearing lifetime.

    Abstract: A first spacer, a second tubular member, and a second spacer are externally fitted and fixed to an outer peripheral surface of a nut. The second tubular member is formed by stacking a plurality of silicon steel plates without any gap, and is arranged between the first spacer and the second spacer axially. The outer diameter of an outer peripheral surface of the second tubular member is made larger than the outer diameter of an outer peripheral surface of the first spacer and the outer diameter of an outer peripheral surface of the second spacer. A detection surface of a first displacement detector is made to radially face a contact portion between the second spacer and the second tubular member, while a detection surface of a second displacement detector is made to radially face a contact portion between the first spacer and the second tubular member.
