摘要:
A thrust roller bearing cage (11) of the present invention is included in a thrust roller bearing (20) and includes a plurality of pockets (21) accommodating rollers (13). The thrust roller bearing cage (11) includes: a radially outer area bent portion (41) formed by bending an area located radially outside the pockets (21) inward in a radial direction; and projecting portions (44) that are formed in a tip end of the radially outer area bent portion (41) and project inward in the radial direction so as to contact end faces (16) of the rollers (13) accommodated in the pockets. Radially outer edges (21a) of the pockets (21) are located radially outside base end parts (44a) of the projecting portions (44).
