To provide a sealed rolling bearing for solving the problem of a pressure difference between the bearing inside and outside, while dispensing with separate processing, without increasing the number of part items.
This sealed rolling bearing includes a seal holder installed in both end parts of an outer ring and a seal member fixed to both end parts of the outer ring by the seal holder and sealing a bearing space formed of the outer ring and an inner ring.
