した軸受め予圧装置。A first magnetic member is fixed to a housing body that rotatably supports a shaft via a rolling bearing, and a preload magnet having one surface facing the first magnetic member with a predetermined gap is provided. A second magnetic member fixed to the shaft and adjacent to the other surface of the preload magnet is also fixed to the shaft, and a magnetic path is formed across the preload magnet and both magnetic members, thereby reducing the preload. A bearing preloading device that attracts a magnet toward a first magnetic member and applies thrust to the shaft in the direction of the attraction to preload a rolling bearing.
