| description | A bearing device includes a shaft and a roller bearing externally inserted over the shaft. The roller bearing includes an inner ring disposed coaxially with a center axis of the shaft, an outer ring surrounding the inner ring from an outer side in a radial direction, and a plurality of rolling elements held between the inner ring and the outer ring to be capable of rolling. The inner ring is divided into one half section and the other half section. The one half section contacts the rolling elements from the one side toward the other side in the axial direction, and the other half section contacts the rolling elements from the other side toward the one side in the axial direction. Preloads are applied to the two half sections in directions in which the one half section and the other half section are brought close to each other. |
