Abstract
In the roller bearing, plural of rollers 15 are interposed between an outer raceway 11 of an outer race 12 and an inner raceway 13 of an inner race 14, and a collar portion 16 is formed along one of the axial-direction end portions of the inner raceway 13. The central portion of one of the outer race and inner raceways 11, 14 and the opposing outer peripheral surface of the roller 15 is formed of a first bus with a given radius of curvature. The two end portion sides adjacent to the central portion are formed of a second bus with such a radius of curvature that causes the two end portion sides to part away from the other. The collar surface 19 of the collar portion 16 contacting with an end face of the roller 15 being a convex-shaped spherical surface is formed as a concave-shaped spherical surface.
