Provided is a double-row rolling bearing (1), including: an outer member (2) having two raceway surfaces (6, 6) on an inner circumference thereof; an inner member (3) having two raceway surfaces (7, 7) on an outer circumference thereof, the inner member (3) being arranged on an inner side of the outer member (2); two rows of rolling elements (4, 4) assembled into a space between each of the two raceway surfaces (6, 6) of the outer member (2) and each of the two raceway surfaces (7, 7) of the inner member (3); and a retainer (5) for retaining the rolling elements (4), any one of the outer member (2) and the inner member (3) including a pair of raceway rings (3a, 3b), both the pair of raceway rings (3a, 3b) being fastened with a fixing bolt (16), the pair of raceway rings (3a, 3b) having positioning holes (13a, 13b) into which a positioning member (14, 14') is fit-inserted, to thereby suppress misalignment in a radial direction of the pair of raceway rings (3a, 3b).
