For a double-row needle roller, characterized in that the outer diameter of the pillar portion having the holding portion is smaller than the outer diameter of the pillar portion having the needle roller holding portion of the flange portion formed at both ends of the retainer. retainer. (2) Utility model registration claim 1, characterized in that more surface depressions are formed on the needle roller holding portion on the left and right sides of the central annular portion than on the flanges on both ends of the cage. Cage for double row needle rollers as described. (3) The pocket width of the needle roller holding part when surface pressing is not performed is wider on the left and right sides of the central annular part than the pocket width of the flange parts on both ends of the cage. A cage for a double-row needle roller according to claim 1, which is a registered utility model.
