Abstract:
Retainer-equipped rollers comprising: a pair of ring parts (11); a retainer (12) having a plurality of column parts (21) extending in the axial direction and connecting the ring parts (11) to each other; and a roller arranged in a pocket between the column parts (21, 21) adjacent to each other in the circumferential direction. The column parts (21) include an end section (22) provided on the outside in the axial direction, and a center section positioned on the inner-diameter side of the end section (22); outer hooks (25), which protrude toward the pocket side and make contact with the roller to restrict the movement of the roller toward the outside in the radial direction, are formed on the end section (22). An oil groove (31), which extends in the circumferential direction and communicates with the outer hooks (25), is formed on an inner-radial surface (26) of the end section (22) of the column parts (21).
