Method of molding a resin coated bearing, method of manufacturing a resin coated bearing, and a resin coated bearing molded by the molding method

A method of molding a resin coated bearing, in which a coating member of a synthetic resin is formed on an outer peripheral surface of a metallic outer race of a ball bearing by insert-molding,

• wherein after a hole defined by an inner peripheral surface of the outer race is fitted onto a columnar portion provided on a first die of forming dies, a second die of the forming dies is brought to cover the second die so that:
• a cavity is defined by an outer periphery of the outer race, the first and second dies;
• a disk space in the form of a disk as viewed in plan view is defined between the columnar portion of the first die and the second die at the time of such covering;
• and
• a film gate is defined to provide communication between a whole edge of an outer periphery of the disk space and the cavity, and
• wherein a molten resin is filled into the cavity through the film gate after the molten resin is led to the disk space from a pin gate, which is formed at a lower end of a sprue formed on the second die when the molten resin is injected toward a substantially central portion of the disk space from the sprue.
