A thrust roller bearing assembly includes first and second raceway members (1, 2), a plurality of rolling elements (4), and a generally plate-like annular roller retainer (3) having a plurality of pockets (7) defined therein in a circumferentially extending row. The rolling elements (4) are rollingly accommodated within the corresponding pockets (7), and each of the pockets (7) is delimited by opposite side faces (7a) and opposite end faces (7b). A plurality of projections (8, 9) are formed in each of the opposite side faces (7a) defining the respective pocket (7) in the roller retainer (3), so as to protrude into the respective pocket (7). Some (8) of the projections (8, 9) in each of the opposite side faces (7a) being formed with respective roller retaining pawls (11) positioned adjacent one principal surface of the retainer (3) while the remaining projections (9) are formed with respective roller retaining pawls (12) positioned adjacent the other principal surface of the retainer (3). All of the projections (8, 9) have respective surfaces which are used as guide faces (8a, 9a) for the rolling elements (4).
