    摘要: A roller bearing cage 10 includes ring portions 11 and pillar portions 12 extend in an axial direction to connect the ring portions 11 and disposed along a circumferential direction to define pocket portions 13. The pillar portion 12 includes a bent portion 12A formed in the vicinity of an axial center of the pillar portion 12 so as to protrude radially inwards of the ring portions 11. A ring portion thickness H1 is larger than a bent portion thickness H2; a pillar end portion thickness H4 is larger than the bent portion thickness H2; and the pillar end portion thickness H4 is equal to the ring portion thickness H1 or more, where the ring portion thickness H1 is a radial thickness of the ring portion 11; the bent portion thickness H2 is a radial thickness of the bent portion 12A; and the pillar end portion thickness H4 is a thickness of a portion of the pillar portion 12 connected to the ring portion 11 and in the vicinity thereof.
