PURPOSE: To reduce processing manhour of an inner race and reduce assembling manhour of respective parts for a housing by forming the inner race from metal, forming one of ring members from synthetic resin, and integrally molding the inner race and the ring member. CONSTITUTION: A cylindrical part 14 is formed in the internal circumferential part of a ring retainer 8 and an inner race 2 is integrally molded around its outer circumferential part. a spline 17 which is fitted into a spline 16 integrally formed in a cylindrical fixed shaft 15 is integrally molded in the internal circumferential face of the cylindrical part 14 in resin molding. The ring retainer 8 is thus in the fixed state along with the inner race 2 so as to be eliminated from axially moving by axial load nor necessitating a thrust needle bearing as the conventional one and therefore the number of parts can be reduced. The spline for fitting into the spline shaft is integrally molded in resin molding so that processing manhour for the inner race can be reduced. |
