PROBLEM TO BE SOLVED: To provide a bearing device capable of improving assembling performance and reducing sliding resistance generated during the rotation of a shaft. SOLUTION: The bearing device 10 includes a plurality of a pair of bearings 11a, 11a supporting the shafts 6 of a plurality of valves 5, and connecting parts 20x, 30y, 20z connecting the bearings 11a, 11a with each other. The connecting parts 20x, 20z are formed to be elastically deformable, and include curved parts 20a formed curved so as to absorb forces acting at least on one of axial and radial directions of the shafts 6. During the installation of the bearing device 10, the connecting parts 20x, 20z are elastically deformed. After the installation of the bearing device 10, upon rotating the shaft 6, the connecting parts 20x, 20z are elastically deformed, and forces acting on at least one of the axial and radial directions of the shafts 6 is absorbed by the curved parts 20a.
