Abstract
A rolling bearing unit includes an outer race and an inner race between which a bearing space is defined; and a circular annular seal member covering a side opening of the bearing space. The circular annular seal member is constituted by a plurality of circumferentially divided seal member parts circumferentially adjacent to each other, and coupled together as a circular annular coupled member by coupling pieces. The seal member includes a distance adjuster capable of adjusting the circumferential distance between a pair of connection portions where the seal member parts are connected to one of the coupling pieces.
