を有することを特徴とする軸受の予圧調整装置。In rolling bearing devices that are used with preload, there are two types of holes: holes with different diameters in the circumferential direction formed concentrically around the shaft center on the bearing housing, and holes that are inserted through the shaft and have diameters as described above. A spacer is provided with a curved protrusion that can be freely engaged with the deceased and a rotating protrusion formed on the inner diameter of the deceased, and is interposed between this spacer and the outer ring of the bearing to constantly push them apart. 1. A preload adjustment device for a bearing, comprising a preload spring that applies an elastic force in a certain direction.
