Abstract

PURPOSE: To heighten productivity, by improving workability in case of modling by shaping a one-sided ball bearing inserting portion by synthetic resin, by inserting a matallic ring between ball bearing supporting portion and a ball bearing and by supporting the ball bearing.
CONSTITUTION: When molding, a supporting portion 8a of a one-sided ball bearing 6 is installed by a mold 15 and synthetic resin 8 while a metallic ring 17 is inserted to the supporting portion after molding, and the ball bearing is supported through the metallic ring 17. With the metallic ring 17, the material belongs to the same kind as the ball bearing 6, the inner diameter is conformed to the dimension of a fitting portion with the ball bearing 6 and finished high accuracy and a plurality of projections 17a are mounted to the outer circumference. The metallic ring 17 is supported to the supporting portion 8a of the ball bearing 6 by using the spring action. Thus, molding can easily be performed while the ball bearing 6 can be operated in a method ensuring high reliability.
