PROBLEM TO BE SOLVED: To provide a divided roller bearing which can suppress the skewing of rollers by means of an outer race, and also can prevent the drop out of the rollers from a retainer in the absence of a bearing ring. SOLUTION: The divided roller bearing comprises the outer race 1 which has flange portions 2a, 2b at both its end portions in the axial direction so as to project toward its axis, a plurality of rollers 3 arranged along the raceway surface of the outer race 1, and a retainer 5 for retaining the rollers 3. The retainer 5 is configured so that the retainer 5 comprises a thick body portion 6 having the outside diameter larger than the inside diameters of the flange portions 2a, 2b of the outer race 1, retainer flange portions 7a, 7b which are provided in the lower portions of both end portions of the body portion 6 in the axial direction and have the outside diameters smaller than the inside diameters of the flange portions 2a, 2b of the outer race 1, pockets which are arranged at a required interval in the peripheral direction of the body portion 6 so as to reach a part of the retainer flange portions 7a, 7b, and roller holders formed at upper and lower portions of the inside walls of the pockets so as to oppose to each other.
