To provide a roller bearing cage which can tightly bind the first and second annular members together without moving the second annular member both axially and circumferentially, and a roller bearing equipped with the cage.

The roller bearing cage separately comprises the first annular member 30 including the first annular part 21 and the second annular member 40 including the second annular part 22. In the first/second annular members 21, 22, the first separation column 32 and the second separation column 42 for separately comprising the first column 27 in an axial direction are formed. In the first separation column 32, a meshing connecting piece 33 with a pawl 34 on the tip which extends along outer or inner diametral plane of the second separation column 42 is formed. On the outer or inner diametral plane of the second separation column 42, a meshing gullet 43 into which the meshing connecting piece 33 is inserted to inhibit circumferential movement is formed by using press work. In the second annular member 40, an engaging part 44 engaged with the pawl 34 of the meshing connecting piece 33 to inhibit axial movement is formed.
