To prevent autorotating skid of a rolling element in a non-load region with a simple structure while avoiding accurately manufacturing a rolling bearing.
Dimensions of inner and outer raceways 1 and 2 and the rolling element 3 are set so that a radial gap is positive; and a region is formed where the rolling element 3 is brought into contact with both of a projecting part of a ring shaped preload imparting body 6 fitted in a peripheral groove 1a formed on the raceway 1 and a raceway 2 on the opposite side, and the rolling element 3 revolves while compressing the preload imparting body 6; and the bearing is used so that the region is positioned in the non-load region. Thus, the rolling element 3 can obtain rotation force in the non-load region.
