Abstract
A roller bearing includes an outer ring formed by connecting a plurality of arc-shaped outer ring members in a circumferential direction and a plurality of rollers arranged along an inner diameter surface of the outer ring. A slope surface (22i) is provided at one or each circumferential end on an inner diameter surface of the outer ring member (22a), and a contour line of the slope surface (22i) is along a direction perpendicular to a revolution direction of the roller.
