The wind/tidal power generation bearing for supporting a main shaft of a wind power generator or a main shaft of a tidal power generator includes a rolling bearing including an inner ring, an outer ring and a plurality of rollers disposed between the inner ring and the outer ring. The plurality of rollers are arranged in a circumferential direction such that axes of alternate rollers or alternate sets of a plurality of rollers intersect each other., thereby reducing a bearing width as compared to a double row tapered roller bearing or the like of the conventional art. Therefore, in the wind power generator or the tidal power generator, a space in an axial direction can be saved as compared to the conventional art. |
