Abstract

PURPOSE: To effectively prevent leakage of sealed grease and entrance of foreign material into a conical roller bearing retainer by integrally forming thick portion or sealing piece projected from one end of the retainer toward an inner race to form a seal with the collar of large diameter at the inner race.
CONSTITUTION: A retainer 21 incorporates a thin sealing piece 25 of polymer or the like formed integrally with the piece 25 at the inner peripheral surface of large diameter side and a slit 26 provided peripherally in a number of tongs for ready molding of the retainer 21. When the retainer 21 is pulled out in the direction of an arrow from upper and lower molds 31 and 32 to exhaust the retainer 21 molded therebetween, the piece 25 engaged with the recess 33 of the lower mold 32 is elastically deformed toward the lower mold 32 to be thus pulled out. It is improtant that the step T at the edges of the openings at the recess 33 of the lower mold 32 is larger than the thickness t of the piece 25.
