A roller bearing comprises an outer ring formed by continuously arranging circular arc-shaped outer ring members in the circumferential direction and rollers disposed along the inner diameter surface of the outer ring. A slope surface (22i) is formed on the inner diameter surface of the outer ring member (22a) at at least one end in the circumferential direction, and the contour line of the slope surface (22i) is directed in the direction orthogonal to the revolution direction of the rollers. L'invention concerne un roulement à rouleaux qui comprend une bague externe formée par la disposition continue d'éléments de bague externe en forme d'arc de cercle dans la direction périphérique et des rouleaux disposés le long de la surface de diamètre interne de la bague externe. Une surface en pente (22i) est formée sur la surface de diamètre interne de l'élément de bague externe (22a) à au moins une extrémité dans la direction périphérique, et la ligne de contour de la surface en pente (22i) est dirigée dans la direction orthogonale à la direction de révolution des rouleaux.
