ABSTRACT:
A roller made of a synthetic resin, used for a belt-conveyor, by means of utilizing insert-forming injection molding, placing a thin-walled metallic housing for containing a roller bearing therein, at the innermost boss portion, for concentrically forming a roller body integrally with the metallic housing. The inner race of the bearing is press-fitted onto the roller shaft, and the outer race thereof is press-fitted inside the metallic housing. A roller of such a construction will resist or absorb most of the inherently large thermal expansion and contraction of a synthetic resin made article, and thus enables the life of the resin made rollers to be elongated far beyond expectation.
