軸受におけるころ脱落防止具。[Claims for Utility Model Registration] A roller that is inserted inside an inner ringless roller bearing in which an annular row of rollers is self-retained on the inner circumferential surface of an outer ring and applies an elastic pressing force radially outward to the annular row of rollers. The drop-off prevention device includes an annular body integrally formed with an elastic groove constricted inward over the entire axial length at a portion of the circumference, and the groove on the periphery of one axial end of the annular body. A device for preventing rollers from falling off in a roller bearing, comprising a flange that integrally extends outward in a radial direction except for a portion of the flange.
