保持器。[Claims for Utility Model Registration] In a cage for a roller bearing having a configuration in which a first annular plate and a second annular plate are coaxially opposed and connected by a plurality of pins, one end of the pin has the following structure: A parallel male threaded part is screwed into a screw hole formed in the first annular plate, and the other end thereof has a first tapered part whose diameter gradually decreases toward the tip and a steep slope from the tip of the first tapered part. The second diameter is reduced by
tapered portions are formed on the inner side surface portion of the second annular plate, and a first portion of the pin is formed on the inner side surface portion of the second annular plate.
A pin support hole opens with a tapered diameter corresponding to the taper portion, and a pin support hole is provided on the outer side for communicating with the pin support hole and exposing a second taper portion of the pin fitted into the pin support hole. A counterbore is formed in each of the pins, and the parallel male screw portion of the pin is screwed into the screw hole of the first annular plate, and the first
A retainer for a roller bearing, characterized in that a tapered portion is press-fitted into a pin support hole of the second annular plate, and the second tapered portion and the counterbore are welded.
