PROBLEM TO BE SOLVED: To provide a resin retainer configured to prevent an axially intermediate part of a column part from being expanded toward the outer diameter by a centrifugal force.SOLUTION: A resin retainer includes: a pair of circular parts 31, 32 spaced axially; and a plurality of column parts 33 axially connecting the pair of circular parts 31, 32 and spaced circumferentially. The resin retainer includes a pocket 34 formed for rotatably holding a roller 40 by the pair of circular parts 31, 32 and a pair of adjacent column parts 33. The pair of circular parts 31, 32 and the column parts 33 are integrated with each other with resin. A metal reinforcement member 35 is embedded in the column part 33 from one to the other of the pair of circular parts 31, 32. |
