The ceramic bearing has a shape in which a cylindrical bearing is divided into a plurality of parts by a dividing surface in the axial direction, and each of the ceramic bearings is mounted on the inner surface of the rubber. The circumferential length of one rubber along the inner surface of the bearing housing is shorter than 1/2 of the circumferential length of the outer surface of the one ceramic bearing, and the circumferential length of each of the main axial gaps along the inner surface of the bearing housing is shorter than 1/2 of the circumferential length of the outer surface of the one ceramic bearing. A bearing device characterized in that the length is longer than 1/2 of the circumferential length of the outer surface of the one ceramic bearing, and the rubber and the ceramic bearing have the same length in the main axis direction.
