A cage used in a large-size rolling bearing is formed of a plurality of cage segments having a circular-arc shape and arranged in a circular pattern. Each cage segment includes rims opposed to each other and separated from each other at a predetermined interval, and a plurality of cage bars that extend from one of the rims to the other rim and that define pockets which accommodate the rollers and which are arranged in the circumferential direction. Multiple pairs of hook portions, between which the inner ring is sandwiched, are formed so as to project from the rims, and are arranged at predetermined intervals in the circumferential direction. Distal ends of the hook portions are engaged with annular grooves formed in end portions of the inner ring so as be rotatable relative to the inner ring.
